Anas bin Malik (RA) is a Companion from Medina. He was born in Yathrib ten years before the migration. At the time of the splitting of the moon, his age was approximately five years, and he resided in Yathrib. The summary of the narration transmitted from him is:
During the time of the Prophet Muhammad (PBUH), the moon split into two parts and in such a way that the Hira mountain became visible between them. At this moment, he said, “You all be witnesses to this.”
The narrations are as follows:
حدثنا مسدد، حدثنا يحيى حدثنا شعبة، عن قتادة، عن انس، قال: انشق القمر فرقتين.
