A very important event in the life of Prophet Muhammad was the Night of Ascension, known as Isra and Mi'raj, which is believed to have occurred around 621 CE. During this miraculous journey, he was taken from Mecca to Jerusalem and then ascended to the heavens, where he encountered various prophets and received divine instructions, including the command to establish the five daily prayers.
