Al-Qasim was a man who made a lot of mistakes when he talked, and his mother was a slave-mother [umm walad, mother of children]. 'Aishah said to him: What is with you that you don't say the hadith like my nephew does? Indeed I know where you got it from. His mother taught him this, and your mother taught you. And Al-Qasim got upset with her, and when he saw that the tablespread had been brought to her, he got up. She said: Where are you going? He said: I'm going to pray. She said: Sit down. He said: Indeed I am going to pray. She said: Sit down, traitor, indeed I heard the Messenger of Allah (SAW) say: There is no prayer when food is present, nor when the akhbathan urge him [evil things, devils; i.e. the need to relieve oneself].
