"We entered upon Jabir bin 'Abdullah and I said: 'Tell me about the Hajj of the Prophet. He said: 'The Messenger of Allah stoned the Jamart which is by the tree, with seven pebbles, saying the Takbir with eeach pebble - pebbles that were the size of data stones or fingertips. And he threw them for the bottom of the valley, then he went to the place of sacrifice in Mina."'  

أَخْبِرْنِي عَنْ حَجَّةِ النَّبِيِّ ﷺ فَقَالَ إِنَّ رَسُولَ اللَّهِ ﷺ رَمَى الْجَمْرَةَ الَّتِي عِنْدَ الشَّجَرَةِ بِسَبْعِ حَصَيَاتٍ يُكَبِّرُ مَعَ كُلِّ حَصَاةٍ مِنْهَا حَصَى الْخَذْفِ رَمَى مِنْ بَطْنِ الْوَادِي ثُمَّ انْصَرَفَ إِلَى الْمَنْحَرِ فَنَحَرَ  

"We returned during the Hajj with the Prophet and some of us said that they had stoned (the Jamarat) with seven stones, and other said that they had done so with six, and no one denounced anyone else."  

سَعْدٌ رَجَعْنَا فِي الْحَجَّةِ مَعَ النَّبِيِّ ﷺ وَبَعْضُنَا يَقُولُ رَمَيْتُ بِسَبْعِ حَصَيَاتٍ وَبَعْضُنَا يَقُولُ رَمَيْتُ بِسِتٍّ فَلَمْ يَعِبْ بَعْضُهُمْ عَلَى بَعْضٍ  

"I heard Abu Mijlaz say: 'I asked Ibn 'Abbas something about the Jimar, and he said: I do not know, the Messenger of Allah stoned it with six or seven.  

مَا أَدْرِي رَمَاهَا رَسُولُ اللَّهِ ﷺ بِسِتٍّ أَوْ بِسَبْعٍ
