Related Ahadith:

Suhaib (RA) reported that Allah's Messenger (SAW) sai "Strange are the ways of a believer for there is good in every affair of his and this is not the case with anyone else except in the case of a believer for if he has an occasion to feel delight, he thanks (Allah), thus there is a good for him in it, and if he gets into trouble and shows resignation (and endures it patiently), there is a good for him in it. [Sahih Muslim, 2999]

It was narrated that Abu Hurairah said: "The Prophet (SAW)) said: 'The strong believer is better and more beloved to Allah than the weak believer, although both are good. Strive for that which will benefit you, seek the help of Allah, and do not feel helpless. If anything befalls you, do not say, "if only I had done such and such" rather say "Qaddara Allahu wa ma sha'a fa'ala (Allah has decreed and whatever he wills, He does)." For (saying) 'If' opens (the door) to the deeds of Shaithan.'" [Sunan Ibn Majah, 79]

Narrated Abu Huraira: The Prophet (SAW) said, "Take refuge with Allah from the difficulties of severe calamities, from having an evil end and a bad fate and from the malicious joy of your enemies." [Sahih al-Bukhari 6616]
