Fiqh al-Sadaqa — The Jurisprudence of Voluntary Charity: Sadaqa, Waqf, Infaq, and the Ethics of Giving

Sadaqa: The Breadth of the Concept

The Quran commands spending in the path of Allah in dozens of verses. “You will never attain righteousness until you spend from what you love” (3:92) — this was revealed and Abu Talha immediately gave his most beloved garden. The jurisprudence of sadaqa derives from:

• Al-infaq: spending generously from one’s wealth (2:177, 2:195, 2:274)
• Al-‘ataa: the gift given freely
• Al-hiba: gift given to a specific recipient
• Al-sadaqa al-‘amma: general charity for community benefit

Sadaqa Jariya: The Enduring Charity

The Prophet taught: “When a person dies, their deeds come to an end except for three: ongoing charity (sadaqa jariya), knowledge that benefits others, and a righteous child who prays for them.” (Muslim)

Sadaqa jariya is thus a financial act with eschatological consequences — the reward continues as long as people benefit. Classic examples: building a well, planting a tree, copying a book of knowledge, funding a teacher, endowing a hospital. In the modern context: creating a website of Islamic knowledge, funding a scholarship, building a community center.

Al-Waqf: Islamic Endowment Law

The waqf (permanent endowment) is sadaqa’s most institutionalized form. A founder (waqif) dedicates property permanently for religious or charitable purposes — the principal is preserved, only the usufruct is used. The Ottoman waqf system funded mosques, madrasas, soup kitchens, caravanserais, hospitals, and water systems across an empire.

Conditions of a valid waqf:

1. The endowed property must be of a type that can generate permanent benefit
2. The purpose must be charitable or religious (not forbidden)
3. The dedication must be permanent — the founder cannot reclaim the property
4. A beneficiary or class of beneficiaries must be specified

The Adab of Giving

The Quran specifies: “Those who spend their wealth in the way of Allah, then do not follow up their spending with reminders of it or harm — their reward is with their Lord” (2:262). The mann (mentioning the gift to create obligation) and adha (harming the recipient’s dignity) invalidate the moral value of the gift even if the act itself stands.
