pay the Zakah

{ Your ally is none but Allāh and [therefore] His Messenger and those who have believed - those who establish prayer and give zakāh, and they bow [in worship]. }

{ And establish prayer and give zakāh and obey the Messenger - that you may receive mercy. }

{ And abide in your houses and do not display yourselves as [was] the display of the former times of ignorance. And establish prayer and give zakāh and obey Allāh and His Messenger. Allāh intends only to remove from you the impurity [of sin], O people of the [Prophet's] household, and to purify you with [extensive] purification. }
