سنن النسائي

It was narrated from Jabir that the Messenger of Allah (ﷺ) went to As-Safa and climbed up it and said: "La ilaha illallah, Wahdahu la sharika lah, lahul-mulku wa lahul-hamdu, yuhyi wa yumitu, wa huwaala kulli shayin qadir (There is none worthy of worship except Allah alone with no partner or associate, His is the dominion and to Him be praise, He gives life and death, and He has power over all things)." Then he walked until he reached level ground, then he hastened until the ground began to rise. Then he walked until he came to Al-Marwah, and he did the same there as he had at As-Safa, until he had finished his Sai."
