In the name of God, Most beneficent, Most Merciful
God says in the holy Qura'n:"

And perform As-Salât (Iqâmat-as-Salât), and give Zakât, and whatever of good (deeds that Allâh loves) you send forth for yourselves before you, you shall find it with Allâh. Certainly, Allâh is All-Seer of what you do. (Al-Baqarah 110).

(1) Successful indeed are the believers. (2) Those who offer their Salât (prayers) with all solemnity and full submissiveness. (3) And those who turn away from Al- Laghw (dirty, false, evil vain talk, falsehood, and all that Allâh forbidden). (4) And those who pay the Zakât. (Al- Mu'minûn 1-4)

And let not those who covetously withhold of that which Allâh has bestowed on them of His Bounty (Wealth) think that it is good for them (and so they do not pay the obligatory Zakât). Nay, it will be worse for them; the things which they covetously withheld shall be tied to their necks like collar on the Day of Resurrection. And to Allâh belongs the heritage of the heavens and the earth; and Allâh is Well-Acquainted with all that you do. (Al' Imrân 180).
