Narrated 'Urwa: I asked 'Aisha : ...But in fact, this divine inspiration was revealed concerning the Ansar who used to assume “Ihram” for worshipping an idol called “Manat” which they used to worship at a place called Al-Mushallal before they embraced Islam, and whoever assumed Ihram (for the idol), would consider it not right to perform Tawaf between Safa and Marwa.
