This chapter was revealed in Mecca and consists of 20 verses. The chapter orders to Prophet to perform the night prayer in order to prepare himself for receiving the weighty speech—the Qur’an—which is revealed to him. It also commands him to be patient with what the people say—that he is a poet, a soothsayer, a lunatic and so on. He is instructed to retire from them gracefully. The chapter also includes some threat and warning to the disbelievers. The initial instructions to the Prophet are extended to the rest of the believers, but they are reduced in the last verse. This chapter was one of the very first chapters revealed to the Prophet in Mecca, called al-ʿatāʾiq (the ancient ones). It is said that it was the second or the third chapter that was revealed to the Prophet.
