إن الصفا والمروة من شعائر الله فمن حج البيت أو اعتمر فلا (2:158) بالانجليزي

(2:158) Indeed Safa and Marwah are among the emblems of Allah: it is, therefore, no sin for him, who performs Hajj or `Umrah *157 to the House of AIIah, to run between the two hills; *158 and Allah knows and appreciates him who does any good with a willing heart. *159

*157). The pilgrimage to the Ka'bah along with a set of other rites on certain fixed dates of Dhu al-Hijjah is known as hajj. Pilgrimage at other times is known as 'Umrah.
*158). Safa and Marwah are the names of two hillocks near the Holy Mosque in Makka. To run between these two hillocks was among the rites which God had taught Abraham in connection with hajj. Later, when Pagan Ignorance prevailed in Makka and the neighbouring regions, altars were built for Isaf at Safa and for Nai'lah at Marwah, and people began to circumambulate them. After the advent of the Prophet, when the light of Islam had spread to the people of Arabia, Muslims came to doubt whether running between Safa and Marwah was one of the original rites of Pilgrimage or was merely an invidious religious innovation of the Age of Ignorance. If it was in fact such, they feared they might be committing an act of polytheism.
Moreover, we learn from a Tradition transmitted from 'A'ishah that even in pre-Islamic times the oeople of Madina were not favourably disposed to this practice. Although they believed in al-Manat they did not believe in Isaf and Nai'lah. For these reasons, it was necessary, at the time of the change of the qiblah, to dispel popular misconceptions about this rite. It seemed necessary to tell people that running between these two hillocks was part of the original rites of Pilgrimage and that the sanctity, of Safa and Marwah, far from being an invidious innovation of the people of the Age of Ignorance, stemmed from the revealed Law of God.
*159). It is best that one should perform this ritual obligation with wholehearted devotion. But if devotion is lacking one is not thereby exempt from fulfilling one's obligation. One must perform this ritual if only out of a sense of duty.
