Tawatur Absolute Or Possibility Of Fault E.g. Adhan In New Born's Ear
If a Twatur is not established it can never be created later. If It is there, that is, the whole community is accepting and acting upon it, it is definitely not a later creation. Because of this tawatur, the tradition of azan in the new Born could not become an established Sunnah and despite its popularity the scholars rejected it.
