Sahih Muslim Book - 11, Hadith - 2211

حَدَّثَنَا حَسَنُ بْنُ الرَّبِيعِ وَمُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ قَالاَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ عَنِ الشَّيْبَانِىِّ عَنِ الشَّعْبِىِّ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- صَلَّى عَلَى قَبْرٍ بَعْدَ مَا دُفِنَ فَكَبَّرَ عَلَيْهِ أَرْبَعًا. قَالَ الشَّيْبَانِىُّ فَقُلْتُ لِلشَّعْبِىِّ مَنْ حَدَّثَكَ بِهَذَا قَالَ الثِّقَةُ عَبْدُ اللَّهِ بْنُ عَبَّاسٍ. هَذَا لَفْظُ حَدِيثِ حَسَنٍ وَفِى رِوَايَةِ ابْنِ نُمَيْرٍ قَالَ انْتَهَى رَسُولُ اللَّهِ -صلى الله عليه وسلم- إِلَى قَبْرٍ رَطْبٍ فَصَلَّى عَلَيْهِ وَصَفُّوا خَلْفَهُ وَكَبَّرَ أَرْبَعًا. قُلْتُ لِعَامِرٍ مَنْ حَدَّثَكَ قَالَ الثِّقَةُ مَنْ شَهِدَهُ ابْنُ عَبَّاسٍ.

It was narrated from Ash-Sha'bi that the Messenger of Allah (s.a.w) offered the funeral prayer over a grave after (the deceased) had been buried, and he said the Takbir four times. Ash-Shaibani said: "I said to Ash-Sha'bi: 'Who told you that?' He said: 'The trustworthy one, 'Abdullah bin 'Abbas."' This is the wording of the Hadith of Hasan. According to the report of Ibn Numair he said: "The Messenger of Allah (s.a.w) came to a fresh grave and offered the funeral prayer, and they formed rows behind him, and he said the Takbir four times." I said to 'Amir: "Who told you that?" He said: "The trustworthy one who saw him, Ibn 'Abbas."
