´It was narrated that Jabir said:` "When he went tout the Masjid heading for As-Safa, I heard the Messenger of Allah say: We will start with that with which Allah started.'"
Hafiz Muhammad Ameen
At that time, Safa and Marwah were outside the mosque. Nowadays, they have come within the boundaries of the mosque, and in fact, quite far inside. (For further details, see Hadith: 2964)
