Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) narrates: (Once) the Prophet (peace and blessings be upon him) ate meat from the shoulder (of an animal), then prayed and did not perform ablution again.
Imam Abu Ya'la and Imam al-Bazzar recorded this report; its chain contains a narrator, Husam bin Missakk, and the hadith scholars agree that he is da'if (weak).
