What did the Prophet Muhammad (saw) say about those who neglected to attend the `Isha' prayer?
 Narrated Abu Huraira:                     Allah's Apostle said, "By Him in Whose Hands my life is, I was about to order for collecting fire wood and then order someone to pronounce the Adhan for the prayer and then order someone to lead the people in prayer and then I would go from behind and burn the houses of men who did not present themselves for the (compulsory congregational) prayer. By Him in Whose Hands my life is, if anyone of you had known that he would receive a bone covered with meat or two (small) pieces of meat present in between two ribs, he would come for `Isha' prayer." (See Hadith No. 617, Vol. 1)
