۞ إِنَّ ٱلصَّفَا وَٱلْمَرْوَةَ مِن شَعَآئِرِ ٱللَّهِ ۖ فَمَنْ حَجَّ ٱلْبَيْتَ أَوِ ٱعْتَمَرَ فَلَا جُنَاحَ عَلَيْهِ أَن يَطَّوَّفَ بِهِمَا ۚ وَمَن تَطَوَّعَ خَيْرًۭا فَإِنَّ ٱللَّهَ شَاكِرٌ عَلِيمٌ
Lo! (the mountains) As-Safa and Al-Marwah are among the indications of Allah. It is therefore no sin for him who is on pilgrimage to the House (of Allah) or visiteth it, to go around them (as the pagan custom is). And he who doeth good of his own accord, (for him) lo! Allah is Responsive, Aware.
Surah Al-Baqara(2:158)
