Whosoever does a good deed.

 

413. Abu Dharr (May Allah be pleased with him) reported: The Prophet (sal Allahu alaihi wa sallam) said, "Allah, the Almighty, says: `Whosoever does a good deed, will have (reward) ten times like it and I add more; and whosoever does an evil, will have the punishment like it or I will forgive (him); and whosoever approaches Me by one span, I will approach him by one cubit; and whosoever approaches Me by one cubit, I approach him by one fathom, and whosoever comes to Me walking, I go to him running; and whosoever meets Me with an earth-load of sins without associating anything with Me, I meet him with forgiveness like that".
[Muslim]
Commentary: This Hadith mentions the infinite Compassion and Mercy of Allah to His obedient slaves and a special expression of which will be made by Him on the Day of Resurrection. On that Day, He will give at least ten times reward for each good deed. In some cases it may be far more than that, seven hundred times or more, as He would like. Such benevolence on His part warrants that a Muslim should never lose hope of His forgiveness.
