Quran 58:13 — The Debate (Al-Mujaadalah)

If you failed to give to charity before conferring, then repented thereafter, GOD accepts your repentance. You shall observe the contact prayers (Salat), give the obligatory charity (Zakat), and obey GOD and His messenger. GOD is fully Cognizant of everything you do.

[58:12] O you who believe, when you wish to confer with the messenger, you shall offer a charity (to the poor) before you do so. This is better for you, and purer. If you cannot afford it, then GOD is Forgiver, Most Merciful.

[58:14] Have you noted those who befriended people with whom GOD is angry? They neither belong with you, nor with them. They deliberately swear lies!
