Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) said, "There is no reality in tiyarah (superstitious omen), haamah (the belief in the owl as a bad omen), contagiousness, or Safar." A man asked, "O Messenger of Allah (peace be upon him)! We take a scab-ridden goat and leave it among the herd, and then the other goats also become scab-ridden." The Prophet Muhammad (peace and blessings be upon him) said, "Who afflicted the first one with scabies?"
