(434) بَابُ إِذَا ضَرَبَ الرَّجُلُ فَخِذَ أَخِيهِ وَلَمْ يُرِدْ بِهِ سُوءًا
Abu'l-'Aliyya al-Bara' said, "'Abdullah ibn as-Samit passed byme and I gave him a chair. He sat down. I told him, 'Ibn Ziyad has delayedthe prayer. What do you command?' He hit my thigh (and I think he said,'So that it left a mark on me') and then he said, 'I asked Abu Dharr asyou asked me and he hit my thigh as I have hit yours. He said, "Pray theprayer at the proper time, but if you come across some of them, pray withthem and do not say, 'I have already prayed,' and then not pray."'"
