Zakat is a religious obligation, ordering all Muslims who meet the necessary criteria to donate a certain portion of wealth each year to charitable causes.
“And establish prayer and give zakat, and whatever good you put forward for yourselves—you will find it with Allah; surely Allah sees what you do.” Holy Qur’an (2:110)
“وَأَقِيمُواْ ٱلصَّلَوٰةَ وَءَاتُواْ ٱلزَّكَوٰةَ ۚ وَمَا تُقَدِّمُواْ لِأَنفُسِكُم مِّنْ خَيْرٍۢ تَجِدُوهُ عِندَ ٱللَّهِ ۗ إِنَّ ٱللَّهَ بِمَا تَعْمَلُونَ بَصِيرٌ” سورة البقرة، ١١٠
Zakat is based on income and the value of possessions. The common minimum amount for those who qualify is 2.5%, or 1/40 of a Muslim’s total savings and wealth.
