Did you know that the ahl al-sunna wa’l jama’a accept the madhab (school of thought) of the househiold of the prophet which is the madhab that the Ithna’ashari Imami Shia’s follow? This is classified as a fifth madhab to them and they can treat its jurisrudential texts in the same way they do with the other four schools. They should then not disparage it nor deride those who embrace it. I believe brother Muslim 786 in his posts did say that he has spent time at Al-Azhar University at Cairo. You can conirm this with him. The sunni alim Shaykh Salim al-Bishri, head of the Al-Azhar University in the early years of the twentieth century initiated the research. In 1959 the then head of Al-Azhar University the late Shaykh Mahmud Shaltut declared a religious injunction that recognised the Ithna Ashari as an acceptable school of thought. The name of the book to read is Al-Muraja’at (The Right Path). Please see link attached.

In case anyone does come up with the comment, the shi’a do not believe the other four schools of thought can be followed abandoning those from whom Allah has removed all filth and has purified them completely (i.e. ahl al-bayt).
