Supplicating upon encountering a calamity.
It is reported on the authority of Umm Salamah (may Allah be pleased with her) that she said:
I heard the Messenger of Allah (peace and blessings of Allah be upon him) say:
"There is no Muslim who is afflicted with a calamity and says what Allah has commanded him:
“Who say, when a misfortune striketh them: Lo! we are Allah's and lo! unto Him we are returning.” (2:156)
'O Allah, reward me in my affliction,
and compensate me with something better than it,'
except that Allah compensates him with something better than it."
