Musannaf Ibn Abi Shayba 21:518

Muhammad ibn Fudayl narrated to us, from Zakariyya, from al-Sha'bi, from Wahb ibn al-Ajda', that he heard 'Umar saying: "He begins at al-Safa and faces the Qibla, the House (the Ka'bah), then he says the takbir seven times. Between every two takbirs, he praises Allah, extols Him, invokes blessings upon the Prophet, may Allah bless him and grant him peace, and makes requests for himself. And at al-Marwah, he does the same."
