At-Tawbah 9:103

Khuth min amwalihim sadaqatantutahhiruhum watuzakkeehim biha wasalliAAalayhim inna salataka sakanun lahum wallahusameeAAun AAaleem

Take, [O Muḥammad], from their wealth a charity by which you purify them and cause them increase, and invoke [Allāh's blessings] upon them. Indeed, your invocations are reassurance for them. And Allāh is Hearing and Knowing.

Take Sadaqah (obligatory alms) out of their wealth through which you may cleanse and purify them, and pray for them. Indeed, your prayer is a source of peace for them. And Allah is (All-) Hearing, (All-) Knowing.
