Musannaf Ibn Abi Shaybah 552 — Those who did not perform ablution

Abu Ziyad said: I saw Sayyiduna Ibn Abbas (may Allah be pleased with them both) and Sayyiduna Abu Hurayrah (may Allah be pleased with him) waiting for a young goat that was being roasted in the oven to finish cooking. Then Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: "Bring it out, lest our prayer be spoiled" (that is, because of intense hunger). So it was taken out and they all ate from it. Then Sayyiduna Abu Hurayrah began to perform ablution, and Sayyiduna Ibn Abbas (may Allah be pleased with them both) asked: "Have we eaten something impure?" At this Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: "You are better than me and more knowledgeable than me." Then they all prayed.
