"Those who spent their wealth (in Allah's Cause) by night and day, in secret and public, they shall have their reward with their Lord. On them shall be no fear, nor shall they grieve."
[Al Baqarah, 274]
"Take Sadaqah (alms) from their wealth in order to purify them and sanctify them with it." [Al-Tawba, 103]
"Race with one another in hastening towards forgiveness from your Lord (Allah), and Paradise the width whereof is as the width of the heaven and the earth, prepared for those who believe in Allah and His Messengers. That is the Grace of Allah which He bestows on whom He is pleased with. And Allah is the Owner of Great Bounty" [al-Hadeed 57:21]
