If you reject (Allah), Truly Allah has no need of you; but He does not like ingratitude from His servants, if you are grateful He is pleased with you. No bearer of burdens can bear the burdens of another. In the End, to your Lord is your Return, when He will tell you the truth of all that you did (in this life). For He knows well all that is in (menís) hearts.

When some trouble touches man, he cries unto his Lord, turning to Him in repentance; but when He bestows a favour upon him as from Himself, (man ) forgets what he cried and prayed for before, and he sets up rivals to Allah, thus misleading others from Allahís path.

Sura Al Zamar Ayat 7,8
