Sahih Muslim Book - 15, Hadith - 3083

وَحَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِى يُونُسُ عَنِ ابْنِ شِهَابٍ عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ أَنَّ عَائِشَةَ أَخْبَرَتْهُ أَنَّ الأَنْصَارَ كَانُوا قَبْلَ أَنْ يُسْلِمُوا هُمْ وَغَسَّانُ يُهِلُّونَ لِمَنَاةَ فَتَحَرَّجُوا أَنْ يَطُوفُوا بَيْنَ الصَّفَا وَالْمَرْوَةِ وَكَانَ ذَلِكَ سُنَّةً فِى آبَائِهِمْ مَنْ أَحْرَمَ لِمَنَاةَ لَمْ يَطُفْ بَيْنَ الصَّفَا وَالْمَرْوَةِ وَإِنَّهُمْ سَأَلُوا رَسُولَ اللَّهِ -صلى الله عليه وسلم- عَنْ ذَلِكَ حِينَ أَسْلَمُوا فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ فِى ذَلِكَ (إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلاَ جُنَاحَ عَلَيْهِ أَنْ يَطَّوَّفَ بِهِمَا وَمَنْ تَطَوَّعَ خَيْرًا فَإِنَّ اللَّهَ شَاكِرٌ عَلِيمٌ)

It was narrated from Urwah bin Az-Zubair that Aishah told him that before the Ansar became Muslim, they and (the tribe of) (Ghassan) used to enter Ihram for Manat, and they felt reluctant to go between As-Safa and Al-Marwah, because they had been the practice of their forefathers; the one who entered Ihram for Manat did not go between As-Safa and Al-Marwah. They asked the Messenger of Allah (SAW) about that when they accepted Islam, and Allah, the Mighty and Sublime, revealed: ‘Verily, As-Safa and Al-Marwah are of the Symbols of Allah. So it is not a sin on him who performs Hajj or Umrah of the House to perform the going (Tawaf) between them (As-Safa and Al-Marwah). And whoever does good voluntarily, then verily, Allah is All-Recogniser, All -Knower.’
