The greatest Hadith of Aqeedah is an Ahad (single chain narration) Hadith. It is the Hadith in which Jibreel (as) came asking the Messenger of Allah (saw); where the Prophet said: Do you know who the questioner is? They said Allah and His Messenger know best. He said: This is Jibreel who came to teach you your Deen. This is Ahad Hadith (single chain narration) on the Aqeedah, so why do we reject it?
