Book 48: Mortgaging
Overview
Book 48 of Sahih al-Bukhari, titled 'Mortgaging' (Ar-Rahn), outlines the economic, judicial, and military precedents set by the Prophet Muhammad regarding pledges and collateral. The text reveals the austere economic reality of Muhammad's household, noting that he died with his armor mortgaged to a Jewish merchant for basic barley. It establishes legal frameworks for usufruct—allowing a mortgagee to ride or milk a pledged animal provided they pay for its upkeep. Judicially, it sets the standard for property disputes: the claimant must produce two witnesses, or the defendant must swear an oath, with severe divine punishment (Quran 3:77) promised for perjury. Most controversially from a comparative standpoint, Hadith 2411 details Muhammad explicitly calling for the death of Ka'b bin Al-Ashraf for 'harming Allah and His Apostle.' Muhammad bin Maslama volunteers and uses a deceptive negotiation over a loan and mortgaged weapons to lure Ka'b into a vulnerable position before assassinating him. This text thus serves as a foundational source for Islamic commercial law, judicial procedure, and the ethics of warfare and dealing with enemies of the state.

Doctrines Analyzed
Key theological claims identified in this text:
Prophetic Sunnah as Binding Law
Assertion
The everyday actions, commercial transactions, and military commands of Muhammad establish eternal, binding legal and ethical precedents for Muslims.
Evidence from Text
The Prophet (ﷺ) bought some foodstuff on credit for a limited period and mortgaged his armor for it.
Evangelical Comparison
In Islam, the Sunnah (the traditions and practices of Muhammad) is a primary source of law alongside the Quran. Muhammad's act of mortgaging his armor, or his ruling on who feeds a mortgaged animal, becomes binding jurisprudence (Fiqh). In Evangelical Christianity, while the life of Christ is the ultimate moral exemplar, the New Testament distinguishes between the specific cultural/historical actions of Jesus (e.g., wearing sandals, celebrating the Passover) and His universal moral commands. Furthermore, Evangelicalism operates under the New Covenant, where the ceremonial and civil laws of the Old Testament are fulfilled in Christ, shifting the focus from external civil jurisprudence to internal moral transformation by the Holy Spirit.
Sanctioned Deception and Assassination in Warfare
Assertion
It is permissible to use deception and targeted assassination against those who mock or harm Allah and His Prophet.
Evidence from Text
Allah's Messenger (ﷺ) said, 'Who would kill Ka`b bin Al-Ashraf as he has harmed Allah and His Apostle?'... Muhammad bin Maslama said, 'I want a loan of one or two Wasqs of food grains.'... So, Muhammad bin Maslama promised him that he would come to him next time. They... came to him as promised and murdered him.
Evangelical Comparison
This doctrine presents a stark contrast to Evangelical ethics. Hadith 2411 explicitly details Muhammad ordering the death of a critic, and his followers using a deceptive business transaction to lower the victim's guard before murdering him. In contrast, Jesus Christ explicitly commanded His followers to 'Love your enemies and pray for those who persecute you' (Matthew 5:44). When Peter attempted to use violence to defend Jesus, Christ rebuked him, saying 'Put your sword back in its place, for all who draw the sword will die by the sword' (Matthew 26:52). The Kingdom of God in Evangelical theology is not of this world and is not advanced by earthly warfare, assassination, or deception (John 18:36).
Divine Retribution for Perjury
Assertion
Taking a false oath to steal property incurs the eternal wrath of Allah and painful torment.
Evidence from Text
Whoever took a false oath in order to grab somebody's property will meet Allah while Allah will be angry with him.
Evangelical Comparison
The condemnation of false oaths aligns with the biblical Ninth Commandment ('You shall not bear false witness'). However, the theological framework differs. In this text, specific sins like perjury are weighed heavily on a scale of deeds, threatening one's standing before Allah. In Evangelical theology, while perjury is a grievous sin, James 2:10 states that 'whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it.' Therefore, avoiding perjury does not justify a person; only the imputed righteousness of Christ received by faith alone (Sola Fide) can save a person from God's righteous anger.
Comparative Analysis
Theological Gap (Summary)
The text demonstrates a works-based, theocratic system where civil law, military deception, and religious devotion are entirely fused, contrasting sharply with Christ's spiritual kingdom and ethic of enemy-love.
Theological Gap (Explained)
The theological gap between this Hadith and Evangelical Christianity is profound, centering on Christology, ethics, and Soteriology. First, the ethical framework of the Kingdom of God as inaugurated by Jesus is fundamentally non-violent and non-retaliatory. Jesus explicitly forbade His disciples from using violence to defend His honor (Matthew 26:52) and commanded love for enemies (Matthew 5:44). In stark contrast, Hadith 2411 portrays Muhammad as a political and military leader who sanctions the deceptive assassination of Ka'b bin Al-Ashraf simply because Ka'b 'harmed Allah and His Apostle' through his words. This violates the Evangelical understanding of God's sovereignty in vengeance (Romans 12:19). Second, the text reinforces a works-righteousness paradigm where divine favor or wrath is contingent upon strict adherence to civil laws (like oaths and collateral). Evangelicalism teaches Sola Fide—that humanity is utterly incapable of satisfying God's legal demands, and therefore justification is a free gift of grace through faith in Christ's finished work, not through the meticulous observance of commercial or judicial codes.
For All Ages
Imagine you have a bully at school who says mean things about you. Jesus teaches us that we should pray for that bully and show them love, trusting God to handle justice. But in this story, the Prophet Muhammad asks his friends to trick and kill a man who was saying bad things about him. Also, this story talks a lot about rules for borrowing money and animals, and says if you lie in court, God will be very angry. Christians agree lying is bad, but we believe we all do bad things sometimes, and the only way to be right with God is because Jesus took our punishment, not just by following a list of rules.
Friction Points
Sola Scriptura
Elevates the oral traditions and actions of Muhammad to the level of divine, binding law.
Christology / Biblical Ethics
Sanctions deception and murder of enemies, directly contradicting the character of Christ and His commands for the New Testament Church.
Sola Fide
Implies that avoiding specific sins (like false oaths) and performing specific works (like killing enemies) secures one's standing before God.
Semantic Warnings
Terms that have different meanings between traditions:
"Harmed Allah"
In This Text
Insulting, mocking, or politically opposing the Prophet Muhammad and the Islamic message.
In Evangelicalism
God is sovereign and impassible; He cannot be literally 'harmed' by human actions. Sins are an offense against His holiness, but do not diminish His power or being.
Soteriology (Salvation)
Salvation Defined: Escaping the 'painful torment' and anger of Allah in the afterlife.
How Attained: By obeying the Prophet, avoiding major sins like perjury, and defending the honor of Islam.
Basis of Assurance: There is no absolute assurance in this text, only the negative promise that false oaths guarantee Allah's anger.
Comparison to Sola Fide: The text operates on a legalistic framework where human actions (oaths, property disputes) directly determine divine wrath. This opposes Sola Fide, which teaches that believers are justified entirely by the righteousness of Christ imputed to them by faith, independent of their legal or moral performance (Romans 3:28).

Discovery Questions
Open-ended questions to promote reflection:
- I noticed in Hadith 2411 that the Prophet ordered the death of Ka'b for his words, and deception was used to carry it out. How do you reconcile this with the idea of a prophet being a moral example for all time?
- When you read about the severe punishment for a false oath, how do you find peace knowing that we all fail to be perfectly honest at times?
- The concept of a 'mortgage' or 'pledge' is interesting here. If we owe a debt to God for our sins that we cannot pay, who can act as our pledge or guarantor?
Redemptive Analogies
Bridges from this text to the Gospel:
The Mortgage / The Pledge (Ar-Rahn)
A mortgage is a pledge given to guarantee a debt will be paid. The Bible uses this exact economic language for salvation. Because we owe a moral debt to God we cannot pay, Jesus became the 'guarantor of a better covenant' (Hebrews 7:22). Furthermore, God gives believers the Holy Spirit as a 'pledge' or 'deposit' guaranteeing our future inheritance (Ephesians 1:14). Jesus paid the debt so we don't have to forfeit our lives.
Spiritual Weight
Burdens this text places on adherents:
The believer is burdened by the constant threat of Allah's anger for infractions in daily life, such as disputes over property or oaths. There is no resting in a finished work of grace; one's eternal destiny is tied to their daily legal and moral performance.
The necessity to perfectly emulate the Sunnah (even in commercial transactions like mortgaging) places a heavy burden of meticulous religious observance on the believer.
Modern Muslims often feel a deep internal conflict when reading authentic texts where their Prophet sanctions deception and assassination, as this conflicts with innate human conscience and modern ethical standards.
