The Numbre of Takbirs in the Funeral Prayer

It was narrated from Abu Hurairah:

That the Messenger of Allah announced the death of An-Najashi to the people, and he led thme out and arranged them in rows, and said the Takbir four times.

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ نَعَى لِلنَّاسِ النَّجَاشِيَّ وَخَرَجَ بِهِمْ فَصَفَّ بِهِمْ وَكَبَّرَ أَرْبَعَ تَكْبِيرَاتٍ .

It was narrated that Abu Umamah bin Sahi said:

"A woman from among the people of Al-'Awali fell sick and the Prophet was the best in visiting the sick. He said: 'When she dies, inform me.' She died at night and they buried her without telling the Prophet. The following morning he asked about her and they said: we did not like to wake you, O Messenger of Allah.' So he went to her grave and offered the funeral prayer for her and said Takbir four times."'

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي أُمَامَةَ بْنِ سَهْلٍ، قَالَ مَرِضَتِ امْرَأَةٌ مِنْ أَهْلِ الْعَوَالِي وَكَانَ النَّبِيُّ ﷺ أَحْسَنَ شَىْءٍ عِيَادَةً لِلْمَرِيضِ فَقَالَ " إِذَا مَاتَتْ فَآذِنُونِي " . فَمَاتَتْ لَيْلاً فَدَفَنُوهَا وَلَمْ يُعْلِمُوا النَّبِيَّ ﷺ فَلَمَّا أَصْبَحَ سَأَلَ عَنْهَا فَقَالُوا كَرِهْنَا أَنْ نُوقِظَكَ يَا رَسُولَ اللَّهِ . فَأَتَى قَبْرَهَا فَصَلَّى عَلَيْهَا وَكَبَّرَ أَرْبَعًا .
