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.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا نَزَلَ مِنَ الصَّفَا مَشَى حَتَّى إِذَا انْصَبَّتْ قَدَمَاهُ فِي بَطْنِ الْوَادِي سَعَى حَتَّى يَخْرُجَ مِنْهُ
