this great miracle of prophet muhammad (pbuh) is mentioned in the quran: "the hour (of judgment) is nigh, and the moon is cleft asunder." (al-qamar, 1). in addition to this, abdullah ibn mas'ud reported that prophet muhammad split the moon.

according to some hadiths (sayings of prophet), a group of polytheists asked prophet muhammad to split the moon into two to prove his prophethood. he turned to allah and requested that this miracle occur. the moon was immediately split into two by the power and with the permission of allah. one part was seen on mount hira, and the other part was seen right in front of the prophet.
