"The Messenger of Allah only performed the Sa'i of the House and of As-Safa and Al-Marwah to show his strength to the idolaters."
Jami` at-Tirmidhi Book 9, Hadith 56
← Previous Hadith "When the Prophet arrived in Makkah, he performed seven (circuits) of Tawaf around the House. Then he came to the Maqam and said: And take you (people) the Maqam (place) of Ibrahim as a place of prayer. Then he prayed behind the Maqam. Then he came to the (Black) Stone to touch it. Then he said: 'We begin with what Allah began with.' So he began at As-Safa and recited: Indeed As-Safa and Al-Marwah are among the Symbols of Allah."

Jami` at-Tirmidhi Book 9, Hadith 55 Next Hadith → "I saw Ibn Umar walking at the place of Sa'i so I said to him: 'Do you walk at the place of Sa'i between As-Safa and Al-Marwah?' He said: 'If I performed Sa'i, then it is because I saw the Messenger of Allah performing Sa'i there, and if I walked, then it is because I have seen the Messenger of Allah walking. And I am an old man.'"
