Al-Baqara 2:158

Indeed, Safa and Marwah [mounts] are among the symbols of Allah. So whoever performs the pilgrimage or ‘Umra, there is no blame upon him to go between them[69]. And whoever does good voluntarily, then Allah is All-Appreciative, All-Knowing.

[69] Some believers had previously feared that this might be a pagan practice, so Allah confirms that this is among the rites of Islam.

Indeed, aṣ-Ṣafā and al-Marwah are among the symbols[55] of Allāh. So whoever makes ḥajj [pilgrimage] to the House or performs ʿumrah - there is no blame upon him for walking between them.[56] And whoever volunteers good - then indeed, Allāh is Appreciative[57] and Knowing.

[55] Places designated for the rites of ḥajj and ʿumrah.
[56] Some believers had previously feared that this might be a pagan practice, so Allāh confirms that saʿī is among the rites of His religion.
[57] i.e., He rewards generously.

158. Verily! As-Safâ and Al-Marwah (two mountains in Makkah) are of the Symbols of Allâh. So it is not a sin on him who performs Hajj or ‘Umrah (pilgrimage) of the House (the Ka‘bah at Makkah) to perform the going (Tawâf) between them (As-Safâ and Al-Marwah).[32] And whoever does good voluntarily, then verily, Allâh is All-Recogniser, All-Knower.

[32] (V.2:158) See the footnote of (V.14:37).

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.
