Sahih al-Bukhari Book 63, Hadith 74
← Previous Hadith I heard Ibn `Abbas saying, "O people! Listen to what I say to you, and let me hear whatever you say, and don't go (without understanding), and start saying, 'Ibn `Abbas said so-and-so, Ibn `Abbas said soand- so, Ibn `Abbas said so-and-so.' He who wants to perform the Tawaf around the Ka`ba should go behind Al-Hijr (i.e. a portion of the Ka`ba left out unroofed) and do not call it Al-Hatim, for in the pre-Islamic period of ignorance if any man took an oath, he used to throw his whip, shoes or bow in it.

'Ubaidullah forgot the third trait. Sufyan said, "They say it (i.e. the third trait) was to believe that rain was caused by the influence of stars (i.e. if a special star appears it will rain).
