Holy Prophet (S.
Holy Prophet (S.A.) that: "Mahdi is none else but Jesus, the son of Mary." Which purports that the Mahdi of Islam is Hazrat Isa (A.S.). None of the scholars of Ahle-Sunnat have accepted this concept (that Isa is Mahdi) because this tradition contradicts various other traditions of the Holy Prophet (S.A.) which are authentic and continuous. Particularly those traditions in which the Holy Prophet (S.A.) has said that 'He will be from my progeny and from the offspring of Fatema (S.A.)'.
The noted celebrity of Ahle-Sunnat, Imam Qurtubbi (exp. 671 A.H.) in his famous exegesis of Quran i.e. 'At-Tazkera fi Umuril Akhera' has declared that it is a weak tradition because in the reliable traditions of the Holy Prophet (S.A.) it is clearly mentioned that he will be from his own lineage, from the children of Fatema (S.A.). These traditions are much more authentic and reliable than the one in question.
Hence the verdict will be based on the most authentic traditions rather than the weaker ones. Such objections are raised by other Sunni stalwarts too. Like Ibn Qayyim in fiftieth chapter of Al-MunarAl-MunifFil-HadithAs-Sahih waz-Zaeef. And according to Baihaqi, the narrators of this tradition are unknown or unreliable.Also the sequence of tradition is not consistent but is lost from some where in between. This tradition is one of the single reports of Mohammad bin Khalid Junaidi.
Zahabi in his Meezanul-Etedaal in third volume, Pg. No. 535 has decisively stated that Mohammad bin Khalid is an unknown narrator and the traditions related by him are not acceptable. More or less similar thing is indicted by another great scholar Abul HasanAaburi in 'Manaqibush-Shafei'. However the unreliability of narrators and incorrect contents of the traditions prove that it is a spurious tradition.
But despite all such inherent weaknesses some of the Sunni scholars like Ibn Kathir and Qurtubbi have made efforts to prove it a correct tradition by whimsical interpretations and fragile justifications. They have asserted that the Mahdi does not imply a particular person but it is used in its literal sense which means 'guided'. Thus Hazrat Isa (A.S.) is the best guided person though this meaning is not correct in itself.
Those things which are pertinent to this tradition like the events and conditions of last era, commotion and distraught which will be ubiquitous refute this justification were given in order to maintain the credibility of the book i.e.
