Al-Adab Al-Mufrad, Book 41, Hadith 957 (English) ⓘ

Abu'l-'Aliyya al-Bara' said, "'Abdullah ibn as-Samit passed by me and I gave him a chair. He sat down. I told him, 'Ibn Ziyad has delayed the 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 as you asked me and he hit my thigh as I have hit yours. He said, "Pray the prayer at the proper time, but if you come across some of them, pray with them and do not say, 'I have already prayed,' and then not pray."'"

حَدَّثَنَا أَبُو مَعْمَرٍ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ الْوَارِثِ، قَالَ‏:‏ حَدَّثَنَا أَيُّوبُ بْنُ أَبِي تَمِيمَةَ، عَنْ أَبِي الْعَالِيَةِ الْبَرَاءِ قَالَ‏:‏ مَرَّ بِي عَبْدُ اللهِ بْنُ الصَّامِتِ، فَأَلْقَيْتُ لَهُ كُرْسِيًّا، فَجَلَسَ، فَقُلْتُ لَهُ‏:‏ إِنَّ ابْنَ زِيَادٍ قَدْ أَخَّرَ الصَّلاَةَ، فَمَا تَأْمُرُ‏؟‏ فَضَرَبَ فَخِذِي ضَرْبَةً، أَحْسَبُهُ قَالَ‏:‏ حَتَّى أَثَّرَ فِيهَا، ثُمَّ قَالَ‏:‏ سَأَلْتُ أَبَا ذَرٍّ كَمَا سَأَلْتَنِي، فَضَرَبَ فَخِذِي كَمَا ضَرَبْتُ فَخِذَكَ، فَقَالَ‏:‏ صَلِّ الصَّلاَةَ لِوَقْتِهَا، فَإِنْ أَدْرَكْتَ مَعَهُمْ فَصَلِّ، وَلاَ تَقُلْ‏:‏ قَدْ صَلَّيْتُ، فلا أُصَلِّي‏.‏
