Ismail bin Abu Awfa reported,

I asked Ibn Abu Awfa, "Did you see Ibrahim, the son of the Prophet ﷺ?"He replied, "He died as a small child. Had it been decreed that there would be a prophet after Muhammad ﷺ, his son would have lived, but there is no prophet after him."

قلت: لابن أبي أوفى: رأيت إبراهيم ابن النبي ﷺ، قال: مات صغيرا، ولو قضي أن يكون بعد محمد ﷺ نبي عاش ابنه، ولكن لا نبي بعده.
