Sahih Muslim 1277 d
'Urwa b. Zubair reported:
I asked 'A'isha (Allah be pleased with her) ; the rest of the hadith is the same. And in this hadith (these words are also found):" When they (the Companions of the Holy Prophet) asked Allah's Messenger (ﷺ) about this, they said: Messenger of Allah, we felt reluctant to circumambulate between al-Safa' and al-Marwa. Then Allah, the Exalted and Majestic, revealed this verse:" Verily al-Safa' and al-Marwa are among the Signs of. Allah so he who perform Hajj or Umra it is no sin on him if he should circumambulate between them. 'A'isha (Allah be pleased with her) said: Allah's Messenger (ﷺ) laid down this Sa'i between them as Sunnah (of the Holy Prophet). So it is not advisable for anyone to abandon this Sa'i between them.
وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا حُجَيْنُ بْنُ الْمُثَنَّى، حَدَّثَنَا لَيْثٌ، عَنْ عُقَيْلٍ، عَنِ ابْنِ، شِهَابٍ أَنَّهُ قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، قَالَ سَأَلْتُ عَائِشَةَ ‏.‏ وَسَاقَ الْحَدِيثَ بِنَحْوِهِ وَقَالَ فِي الْحَدِيثِ فَلَمَّا سَأَلُوا رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ ذَلِكَ فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّا كُنَّا نَتَحَرَّجُ أَنْ نَطُوفَ بِالصَّفَا وَالْمَرْوَةِ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏ إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلاَ جُنَاحَ عَلَيْهِ أَنْ يَطَّوَّفَ بِهِمَا‏}‏ قَالَتْ عَائِشَةُ قَدْ سَنَّ رَسُولُ اللَّهِ صلى الله عليه وسلم الطَّوَافَ بَيْنَهُمَا فَلَيْسَ لأَحَدٍ أَنْ يَتْرُكَ الطَّوَافَ بِهِمَا.
