Volume II — The Etiquette of Marriage (Adab al-Nikah)

Al-Ghazali's treatment of marriage (nikah) in the Ihya is among the most comprehensive in classical Islamic literature — a rich synthesis of legal rulings, ethical guidance, psychological insight, and spiritual reflection. His starting point is the Quranic declaration that has guided Islamic marital theology since the beginning: 'And among His signs is that He created for you from yourselves mates that you may find tranquility in them; and He placed between you affection (mawaddah) and mercy (rahmah)' (Quran 30:21).

Al-Ghazali begins by presenting the case both for and against marriage, an unusual approach that reflects his philosophical temperament. The case for marriage includes: fulfilling the Sunnah of the Prophet ﷺ (who said 'Marriage is from my sunnah, and whoever turns away from my sunnah is not of me'); the production of offspring to continue the human community and to provide the Muslim ummah with future worshippers; the protection of chastity and the channeling of natural desires within lawful boundaries; and the spiritual and material partnership that a good marriage provides. The argument against that al-Ghazali engages (primarily derived from early ascetics) is that the responsibilities of marriage can distract from religious devotion and spiritual retreat — an argument he ultimately weighs against and concludes that for the vast majority of people, marriage is superior.

His guidance on the choice of a spouse is notable for balancing pragmatic wisdom with spiritual priorities. The Prophet ﷺ said: 'A woman is married for four reasons: her wealth, her family, her beauty, and her religion — so choose the one of religion, and you will prosper.' (Al-Bukhari and Muslim.) Al-Ghazali applies the same logic to a woman's choice of husband: a woman of religious commitment should prioritize a man of religious commitment and good character above wealth and social standing. He notes that the Prophet ﷺ warned: 'If a man comes to you whose religion and character please you, then give him your daughter in marriage; if you do not, there will be corruption and great discord on earth.' (Al-Tirmidhi.)

The chapter's treatment of marital relations is frank, dignified, and grounded in the Sunnah — a remarkable departure from the squeamishness that sometimes characterizes religious discussion of intimate life. Al-Ghazali discusses the pre-intimacy supplications the Prophet ﷺ taught, the importance of mutual pleasure and consideration between spouses, the right of the wife to conjugal relations, and the husband's obligation to treat his wife with kindness even when their personalities differ. He draws extensively on the Prophet's ﷺ example — his gentleness with his wives, his participation in household tasks, his patience with their human limitations, and his declaration: 'The best of you is the one who is best to his family, and I am the best of you to my family.' (Al-Tirmidhi.)

The spiritual dimension that al-Ghazali adds to this legal and ethical framework is his insistence that the family unit, when governed by consciousness of Allah, becomes itself a site of worship. Each kind word between spouses, each act of patient forbearance, each supplication for one's children is an act of nearness to Allah. The home is not a distraction from the spiritual life — it is one of its primary arenas.
