Sayyiduna Anas bin Malik (may Allah be pleased with him) said: "It is the Sunnah that the burial of the deceased is begun from the side of the qiblah, and that the soil is also thrown onto him from the side of the qiblah."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Rabi'ah except Ubaydah, and no one narrated it from Ubaydah except Amr, and Ali bin Harb is alone in narrating it."
