Hadith 2722
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) performed Tawaf of the Ka'bah while riding a camel. When he reached the Black Stone, he would point towards it with something (a stick) in his hand and say « اللهُ أَكْبَرُ ».
