Hadith 324
146- وبه: أن رسول الله صلى الله عليه وسلم كان إذا نزل من الصفا مشى حتى إذا انصبت قدماه فى بطن الوادي سعى حتى يخرج منه.
And with the same chain of narration, it is narrated from (Sayyiduna Jabir bin Abdullah al-Ansari, may Allah be pleased with him) that when the Messenger of Allah, peace and blessings be upon him, would descend from (the hill of) Safa, he would walk until when he reached the middle of the valley, he would run until he had crossed it.
