How Did Prophet Muhammad (sws) Offer Salah During Hajjatul-Wida?
That is why Salah is present in the ijma and tawatur of Muslims because Prophet Muhammad (Sws) instituted Salah as his Sunnah and all Sahaba followed that practice and transmitted it to the next generation. Ijma and Tawatur are not dependant on isolated historical narrations. It is alive among the Muslim ummah and does not need to be documented as individual reports.
