It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that whenever he placed a deceased person in the grave, he would say: 'Bismillah, wa 'ala sunnati Rasulillah' (In the name of Allah, and upon the Sunnah of the Messenger of Allah (peace and blessings be upon him)). The hadith of al-Bayadi, who is well known among the Companions, is a supporting narration (shahid) for the musnad hadith of Hammam from Qatadah.
