Al-Bayhaqi recorded that `Abdullah bin `Umar commented on Allah's statement:

﴿اقْتَرَبَتِ السَّاعَةُ وَانشَقَّ الْقَمَرُ ﴾

(The Hour has drawn near, and the moon has been cleft asunder.) "This occurred during the time of Allah's Messenger ; the moon was split in two parts. A part of it was before the mount and a part on the other side. The Prophet said,

«اللْهُمَّ اشْهَد»

(O Allah! Be witness.)'' This is the narration that Muslim and At-Tirmidhi collected. At-Tirmidhi said, "Hasan Sahih.''
