It is reported from him (Sayyiduna Ali) that he said: Once we began praying with the Prophet (peace and blessings be upon him), when during it the Prophet (peace and blessings be upon him) went away while we remained standing. The narrator then mentioned the rest of the hadith as before. Ahmad, al-Bazzar, and al-Tabarani in al-Mu'jam al-Awsat recorded both these narrations, except that al-Tabarani narrated these words: "That person should go back, perform ghusl (ritual bath), then come and offer the prayer (anew)." All its routes revolve around the narrator Ibn Lahi'ah, about whom there is criticism.
