I heard the Messenger of Allah ﷺ say, "There is no prayer when food is served, nor when one is holding back the two impurities."
سمعت رسول الله ﷺ يقول: لا صلاة بحضرة الطعام، ولا وهو يدافعه الأخبثان.
Muslim narrated it in the Book of Mosques (560) from Yaqub bin Mujahid, from Ibn Abu Atiq, who said, "Qasim and I were talking together at Ayesha's house. Qasim was a man who made frequent grammatical mistakes in his speech, and he was the son of an umm walad (slave mother). Ayesha said to him, "Why don't you speak the way this nephew of mine speaks? I know well where that comes from. This one's mother trained him properly, but your mother trained you."He said, Qasim became angry and held a grudge against her. When he saw that Ayesha's table had been brought in, he got up. She said, "Where are you going?" He said, "I am going to pray." She said, "Sit down." He said, "I am going to pray." She said, "Sit down, ghadr (traitor). I heard the Messenger of Allah ﷺ say..." Then she mentioned the hadith.Abu Hazrah the storyteller also narrated it, from Abdullah bin Abu Atiq, from her, from the Prophet ﷺ, with similar wording.His statement "lahhana" means one who makes frequent grammatical errors in his speech.Her statement, "Sit down, ghadr," carries the meaning of "ghadir" (traitor). In the vocative form of address, one says simply "O ghadr" for a single person, and "O family of ghadr" for a group. Ghadr means abandoning loyalty and faithfulness. She called him "ghadr" because he was duty-bound to show her respect, since she was the Mother of the Believers, his paternal aunt, older than him, sincere in advising him, and one who had disciplined him.
