Hadith- The stong believer

In the Name of Allah, the Most Gracious, the Most Merciful.

Abu Hurayra said that the Messenger of Allah, may Allah bless him and grant him peace, said, "The strong believer is better and more beloved to Allah than the weak believer although there is good in each. Desire that which will bring you benefit, and seek help from Allah and do not give way to incapacity. If something happens to you, do not say, 'If only I had done such-and-such.' Rather say, 'The decree of Allah. He does what He will.' Otherwise you will open yourself up to the action of Shaytan." [Muslim]
