Narrated `Asim:I asked Anas bin Malik: "Did you use to dislike to perform Tawaf between Safa and Marwa?" He said, "Yes, as it was of the ceremonies of the days of the Pre-Islamic period of ignorance, till Allah revealed: 'Verily! (The two mountains) As-Safa and Al-Marwa are among the symbols of Allah. It is therefore no sin for him who performs the pilgrimage to the Ka`ba, or performs `Umra, to perform Tawaf between them.' " (2.158)
حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا عَاصِمٌ، قَالَ قُلْتُ لأَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَكُنْتُمْ تَكْرَهُونَ السَّعْىَ بَيْنَ الصَّفَا وَالْمَرْوَةِ قَالَ نَعَمْ. لأَنَّهَا كَانَتْ مِنْ شَعَائِرِ الْجَاهِلِيَّةِ، حَتَّى أَنْزَلَ اللَّهُ {إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلاَ جُنَاحَ عَلَيْهِ أَنْ يَطَّوَّفَ بِهِمَا}.
