"We complained to the Messenger of Allah on the day of Uhud, saying: 'O Messneger of Allah, it is too difficult for us to dig a grave for each person.' The Messenger of Allah said: 'Dig graves and make them good and deep, and bury two or three in one grave.' They said: 'Who should we put in first, O Messenger of Allah?' He said: 'Put in first the one who knew more Qur'an."' He said: "My father was the third of three in one grave."

أَخْبَرَنِي عَبْدُ الرَّحْمَنِ بْنُ خَالِدٍ الْقَطَّانُ الرَّقِّيُّ، قَالَ حَدَّثَنَا حَجَّاجٌ، قَالَ ابْنُ جُرَيْجٍ أَخْبَرَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرًا، يَقُولُ : خَطَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَذَكَرَ رَجُلاً مِنْ أَصْحَابِهِ مَاتَ فَقُبِرَ لَيْلاً، وَكُفِّنَ فِي كَفَنٍ غَيْرِ طَائِلٍ، فَزَجَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يُقْبَرَ إِنْسَانٌ لَيْلاً إِلاَّ أَنْ يُضْطَرَّ إِلَى ذَلِكَ .
