Mishkat al-Masabih #1570
Funerals
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَعَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى قَالَ: كَانَ زَيْدُ بْنُ أَرْقَمَ يُكَبِّرُ عَلَى جَنَائِزِنَا أَرْبَعًا وَأَنَّهُ كَبَّرَ عَلَى جَنَازَةٍ خَمْسًا فَسَأَلْنَاهُ فَقَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يكبرها. رَوَاهُ مُسلم
‘Abd ar-Rahman b. Abu Laila said that Zaid b. Arqam used to say “God is most great” four times over their dead at funerals, but once he said it five times. On being questioned about it he replied that God's messenger used to do so.
Muslim transmitted it.
