The Pleading Woman - 58:12
O you who believe, when you have a private meeting with the messenger, give a charity before your meeting. That is better for you and purer. If you cannot give, Allah is Forgiving, Merciful.
For whom did the messenger receive the alms?
The Repentance/9:60
Alms, as an obligation from Allah, should be given to the poor, to the needy, to those who labor, to sympathizers, for the freedom of slaves, to debtors, to the way of Allah, and to the wayfarers. Allah is All-Knowing, All-Wise.
