Qur'aanic Verse 2:245:
245. Man tha allathee yuqridu Allaha qardan hasanan fayudaAAifahu lahu adAAafan katheeratan waAllahu yaqbidu wayabsutu wa-ilayhi turjaAAoona
245. Who is there to lend a good loan to Allah, which He will repay in multiples thereof? And it is Allah Who takes possession of things and amplifies them, and to Him you shall be returned.464
464. Magnanimously thus does Allah offer a deal to His creatures, the human beings. HE wants them to sacrifice, if necessary, the pleasures of this worldly life, which are in any case temporary and unreliable. In return, He offers them everlasting rewards, many many times more in real value.
