Sunan an-Nasa'i, Hadith 2981 ⓘ
It was narrated from Jabir bin Abdullah, may Allah be pleased with him, that: when the Messenger of Allah came down from As-Safa he would walk until he reached the bottom of the valley, then he would hasten until he came out of it.
أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، وَالْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ الْقَاسِمِ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، رضى الله عنهما أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا نَزَلَ مِنَ الصَّفَا مَشَى حَتَّى إِذَا انْصَبَّتْ قَدَمَاهُ فِي بَطْنِ الْوَادِي سَعَى حَتَّى يَخْرُجَ مِنْهُ .
