Zakah is the obligatory charity paid from wealth. The Quran pairs it with prayer again and again and says it was part of the religion given to earlier communities. The Torah has its own laws of the tithe and of leaving the harvest for the poor, and the Gospels teach giving alms.
The Quran makes zakah a duty on property and names who may receive it. Prayer and zakah come together in many verses.
Passages are the King James Version unless marked otherwise. Each carries a tag: a close parallel, a shared principle, or an interpretation (Muslim or traditional), which is a reading we offer as a reading and not as a proven fact.
