The Meaning of "it is not a sin'' in the Ayah
Imam Ahmad reported that `Urwah said that he asked `A'ishah about what Allah stated:
[إِنَّ الصَّفَا وَالْمَرْوَةَ مِن شَعَآئِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلاَ جُنَاحَ عَلَيْهِ أَن يَطَّوَّفَ بِهِمَا]
(Verily, As-Safa and Al-Marwah (two mountains in Makkah) are of the symbols of Allah. 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 (Tawaf) between them (As-Safa and Al-Marwah).) "By Allah! It is not a sin if someone did not perform Tawaf around them.'' `A'ishah said, "Worst is that which you said, O my nephew! If this is the meaning of it, it should have read, `It is not a sin if one did not perform Tawaf around them.' Rather, the Ayah was revealed regarding the Ansar, who before Islam, used to assume Ihlal (or Ihram for Hajj) in the area of Mushallal for their idol Manat that they used to worship. Those who assumed Ihlal for Manat, used to hesitate to perform Tawaf (going) between Mounts As-Safa and Al-Marwah. So they (during the Islamic era) asked Allah's Messenger about it, saying, `O Messenger of Allah! During the time of Jahiliyyah, we used to hesitate to perform Tawaf between As-Safa and Al-Marwah.' Allah then revealed:
[إِنَّ الصَّفَا وَالْمَرْوَةَ مِن شَعَآئِرِ اللَّهِ فَمَنْ حَجَّ الْبَيْتَ أَوِ اعْتَمَرَ فَلاَ جُنَاحَ عَلَيْهِ أَن يَطَّوَّفَ بِهِمَا]
(Verily, As-Safa and Al-Marwah are of the symbols of Allah. So it is not a sin on him who performs Hajj or `Umrah of the House to perform the going (Tawaf) between them.)'' `A'ishah then said, " Allah's Messenger has made it the Sunnah to perform Tawaf between them (As-Safa and Al-Marwah), and thus, no one should abandon performing Tawaf between them.'' This Hadith is reported in the Sahihayn.
In another narration, Imam Az-Zuhri reported that `Urwah said: Later on I (`Urwah) told Abu Bakr bin `Abdur-Rahman bin Al-Harith bin Hisham (of `A'ishah's statement) and he said, "I have not heard of such information. However, I heard learned men saying that all the people, except those whom `A'ishah mentioned, said, `Our Tawaf between these two hills is a practice of Jahiliyyah. ' Some others among the Ansar said, `We were commanded to perform Tawaf of the Ka`bah, but not between As-Safa and Al-Marwah.' So Allah revealed:
[إِنَّ الصَّفَا وَالْمَرْوَةَ مِن شَعَآئِرِ اللَّهِ]
(Verily, As-Safa and Al-Marwah are of the symbols of Allah.)'' Abu Bakr bin `Abdur-Rahman then said, "It seems that this verse was revealed concerning the two groups.'' Al-Bukhari collected a similar narration by Anas.
Ash-Sha`bi said, "Isaf (an idol) was on As-Safa while Na'ilah (an idol) was on Al-Marwah, and they used to touch (or kiss) them. After Islam came, they were hesitant about performing Tawaf between them. Thereafter, the Ayah (2:158 above) was revealed.''
