Narrated Ibn Abi Laila: Zaid b. Arqam used to utter four takbirs (Allah is Most Great) over our dead person (during prayer). He uttered five takbirs on a dead person. So I asked him. He replied: The Messenger of Allah (ﷺ) used to utter those. Abu Dawud said: I remember the tradition of Ibn al-Muthanna in a more guarded way.

حَدَّثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ، حَدَّثَنَا شُعْبَةُ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ شُعْبَةَ، عَنْ عَمْرِو بْنِ مُرَّةَ، عَنِ ابْنِ أَبِي لَيْلَى، قَالَ كَانَ زَيْدٌ - يَعْنِي ابْنَ أَرْقَمَ - يُكَبِّرُ عَلَى جَنَائِزِنَا أَرْبَعًا وَإِنَّهُ كَبَّرَ عَلَى جَنَازَةٍ خَمْسًا فَسَأَلْتُهُ فَقَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُكَبِّرُهَا ‏.‏ قَالَ أَبُو دَاوُدَ وَأَنَا لِحَدِيثِ ابْنِ الْمُثَنَّى أَتْقَنُ ‏.‏
