Why would someone be a kaafir if he does not accept that Hawwaa (alayhas salaam) was created from the rib of Nabi Aadam (alayhas salaam)?

Answer

You don't know what you are saying. Do you have any doubt in the Shariah's teaching that Hadhrat Hawwaa (alayhas salaam) was created from the rib of Hadhrat Aadam (alayhis salaam)? Is this teaching not Mutawaatir? Rejection of this absolute truth is kufr. The view of Rabee Bin Anas and Abu Muslim is extremely rare and baatil. It is utterly baseless, and these seniors had erred in their understanding on this issue. In fact, it is mentioned in Umdatul Qaari that this view is 'baatil'. The Tawaatur of this belief is not negated by such rare views. There are rare views on almost every Shar'i issue. Rare views which are in diametric conflict with the official version of the Shariah should never be cited to negate the view of the Jamhoor. Allaamah Sha'raani (rahmatullah alayh) said: "He who takes the rare views of the Ulama (as his daleel), he has made his exit from Islam."
