Ibn Umar said:

"When the Messenger of Allah arrived in Makkah he circumambulated the House seven times, then he prayed two Rakahs behind the Maqam. Then, he went out to As-Safa through the gate that is usually used to exit, and performed Sai between As-Safa and Al-Marwah." (One of the narrators Shubah said: Ayub informed me from Amr bin Dinar from Ibn Umar that he said: "A Sunnah."

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ دِينَارٍ، قَالَ سَمِعْتُ ابْنَ عُمَرَ، يَقُولُ لَمَّا قَدِمَ رَسُولُ اللَّهِ ﷺ مَكَّةَ طَافَ بِالْبَيْتِ سَبْعًا ثُمَّ صَلَّى خَلْفَ الْمَقَامِ رَكْعَتَيْنِ ثُمَّ خَرَجَ إِلَى الصَّفَا مِنَ الْبَابِ الَّذِي يُخْرَجُ مِنْهُ فَطَافَ بِالصَّفَا وَالْمَرْوَةِ . قَالَ شُعْبَةُ وَأَخْبَرَنِي أَيُّوبُ عَنْ عَمْرِو بْنِ دِينَارٍ عَنِ ابْنِ عُمَرَ أَنَّهُ قَالَ سُنَّةٌ .
