A Muslim knows that there is good in everything...

Abu Suhayb ibn Sinaan narrated that the Prophet said:

“How amazing is the case of the believer; there is good for him in everything, and this characteristic is exclusively for him alone. If he experiences something pleasant, he is thankful, and that is good for him; and if he comes across some diversity, he is patient, and that is good for him.”
