Sulaiman b. Buraida narrated on the authority of his father that the Messenger of Allah (ﷺ) used to teach them when they went out to the graveyard. One of the narrators used to say this in the narration transmitted on the authority of Abu Bakr:" Peace be upon the inhabitants of the city (i. e. graveyard)." In the hadith transmitted by Zuhair (the words are):" Peace be upon you, the inhabitants of the city, among the believers, and Muslims, and God willing we shall join you. I beg of Allah peace for us and for you."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ، الأَسَدِيُّ عَنْ سُفْيَانَ، عَنْ عَلْقَمَةَ بْنِ مَرْثَدٍ، عَنْ سُلَيْمَانَ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُعَلِّمُهُمْ إِذَا خَرَجُوا إِلَى الْمَقَابِرِ فَكَانَ قَائِلُهُمْ يَقُولُ - فِي رِوَايَةِ أَبِي بَكْرٍ - السَّلاَمُ عَلَى أَهْلِ الدِّيَارِ - وَفِي رِوَايَةِ زُهَيْرٍ - السَّلاَمُ عَلَيْكُمْ أَهْلَ الدِّيَارِ مِنَ الْمُؤْمِنِينَ وَالْمُسْلِمِينَ وَإِنَّا إِنْ شَاءَ اللَّهُ لَلَاحِقُونَ أَسْأَلُ اللَّهَ لَنَا وَلَكُمْ الْعَافِيَةَ.
