The Prophet (ﷺ) said, “No prayer is heavier upon the hypocrites than the Fajr and the `Isha’ prayers and if they knew what is in them (in reward), they would have attended them, even if (it was) crawling. Certainly, I felt the urge to order the Mu’adh-dhin (call-maker) so that he would pronounce Iqama, then order a man to lead the people (in prayer), then take a flame of fire so that I burn (the houses) upon those who had not left for the prayer yet.”
