The Book on Salutations and Greetings (Kitab As-Salam)

Muslim :: Book 26 : Hadith 5516

Jabir b. 'Abdullah reported Allah's Apostle (may peace be upon him) as saying: There is no transitive disease, no safar, no ghoul. He (the narrator) said: I heard Abu Zubair say: Jabir explained for them the word safar. Abu Zubair said: safar means belly. It was said to Jabir: Why is it so? He said that it was held that safar implied the worms of the belly, but he gave no explanation of ghoul. Abu Zubair said: Ghoul is that which kills the travellers.
