2. Al-Baqara (The Cow)

Surah: 2   Aya: 158

158. Inna alssafa waalmarwata min shaAAa-iri Allahi faman hajja albayta awi iAAtamara fala junaha AAalayhi an yattawwafa bihima waman tatawwaAAa khayran fa-inna Allaha shakirun AAaleemun
  

  Translation

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 perform Hajj or 'Umrah (pilgrimage) of the House (the Ka'bah at Makkah) to perform the going (Tawâf) between them (As-Safâ and Al-Marwah). And whoever does good voluntarily, then verily, Allâh is All-Recogniser, All-Knower.
