Sunan Ibn Majah, Hadith 1479 ⓘ
It was narrated from Abu Musa that the Prophet saw a funeral (procession) with which the people were rushing. He said: “You should move with tranquility.”
حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدِ بْنِ عَقِيلٍ، حَدَّثَنَا بِشْرُ بْنُ ثَابِتٍ، حَدَّثَنَا شُعْبَةُ، عَنْ لَيْثٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ أَنَّهُ رَأَى جِنَازَةً يُسْرِعُونَ بِهَا قَالَ " لِتَكُنْ عَلَيْكُمُ السَّكِينَةُ " .
