What did Prophet Muhammad (peace be upon him) say about Adwa, Hamah, and the month of Safar?
 Narrated Abu Huraira:                     Allah's Apostle said, '(There is) no 'Adwa (no contagious disease is conveyed without Allah's permission). nor is there any bad omen (from birds), nor is there any Hamah, nor is there any bad omen in the month of Safar, and one should run away from the leper as one runs away from a lion.''
