Assalaamu alaikum brothers and sisters,

My father asked me to clarify if there is an ayat of Quran (which signifies the first milaad-un-nabi) where only the Prophets (peace be on them all) and the last nabi Rasul (saws) were assembled and a promise was exacted from all the other prophets that they would give tidings to their followers of the last Prophet Muhammad (saws).
My father is not referring to the Day of Promises where all the souls were present, but uniquely to a different event of an assembly of all the Prophets peace be on them and Rasul (saws).
Please provide me with the ayat reference that he is talking about.

Arif
