Muwatta Malik 828

Yahya related to me from Malik from Jafar ibn Muhammed ibn AIi from his father from Jabir ibn Abdullah that the Messenger of Allah, may Allah bless him and grant him peace, used to say, "Allah is greater" three times when he stopped on Safa, and "There is no god but Allah, alone, without any partner. To Him belong the Kingdom and praise, and He has power over everything" three times, and make dua. He would then do the same on Marwa
