Al-Baqarah 2:158

Inna assafa walmarwatamin shaAAa-iri Allahi faman hajja albaytaawi iAAtamara fala junaha AAalayhi an yattawwafabihima waman tatawwaAAa khayran fa-inna Allahashakirun AAaleem

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

Indeed Safā and Marwah are among the marks of Allah.So whoever comes to the House for Hajj or performs ‘Umrah, there is no sin for him if he makes rounds between them; whoever comes up with good on his own, then Allah is Appreciating, All-Knowing.
