Musannaf Ibn Abi Shaybah

Hazrat Wahb bin Al-Ajda’ narrates that I heard Hazrat Umar saying: The beginning will be made from the Safa hill, and first, face towards the House of Allah (Ka’bah), then say Takbeer seven times, and between every two Takbeers, praise and glorify Allah, send blessings upon the Noble Prophet (peace and blessings be upon him), and supplicate for yourself. And the same will be done at the Marwah hill.
