That a group of Quraysh said to the Messenger of Allah (sa)
"Through what merit do you precede the prophets while you were sent as the last of them and as their seal?"
So he said-
"I was the foremost in bringing faith in my Lord and the first to respond as Allah extracted the testimony of the prophets and [as he] made them witnesses upon their souls, saying 'am I not your Lord?' I was the first prophet to say yes [o Lord]. Thus I preceded them all in giving testimony to Allah"
