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 Kaʿba, or performs ʿUmra, to perform Tawaf between them.' " (2.158)
قُلْتُ لأَنَسِ بْنِ مَالِكٍ ؓ: 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}
