Take Sadaqah (alms) from their wealth in order to purify them and sanctify them with it, and invoke Allâh for them. Verily! Your invocations are a source of security for them, and Allâh is All-Hearer, All-Knower. (9:103)

Know they not that Allâh accepts repentance from His slaves and takes the Sadaqât (alms, charities) and that Allah Alone is the One Who forgives and accepts repentance, Most Merciful? (9:104)
