Musannaf Ibn Abi Shaybah

Hazrat Imran bin Abi Ata states that I was present at the time of the death of Hazrat Abdullah bin Abbas (may Allah be pleased with them), so his funeral prayer was led (the arrangements were made) by Hazrat Ibn al-Hanafiyyah, and he said four takbirs in it and the deceased was lowered into the grave from the direction of the Qiblah.
