Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated ‘Aisha (Radi-Allahu ‘anha):
(the wife of the Prophet (Sallallahu ‘Alaihi Wa Sallam)) I asked Allah’s Apostle (Sallallahu ‘Alaihi Wa Sallam) about the plague. He told me that it was a Punishment sent by Allah on whom he wished, and Allah made it a source of mercy for the believers, for if one in the time of an epidemic plague stays in his country patiently hoping for Allah’s Reward and believing that nothing will befall him except what Allah has written for him, he will get the reward of a martyr.“
