It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that during the blessed era of the Prophet (peace and blessings be upon him), the moon was split into two parts. At that time, we were with the Prophet (peace and blessings be upon him) at Mina, until one part of the moon went behind the mountain. The Prophet (peace and blessings be upon him) said: "Bear witness."
