Surah al-Mulk (The Kingdom)

It was narrated from Abu Hurayrah that the Prophet (Peace and Blessings of ALLAH be upon him) said:
“A surah from the Qur’aan containing thirty verses will intercede for a man so that he will be forgiven. It is the surah Tabaarak Alathi bi yadihi’l-mulk [i.e., Surat al-Mulk].”

It was narrated that ‘Abd-Allaah ibn Mas’ood said:
"Whoever reads Tabaarak allaahi bi yadihi’l-mulk [i.e., Surat al-Mulk] every night, ALLAH will protect him from the torment of the grave. At the time of the Messenger of ALLAH (peace and blessings of ALLAH be upon him) we used to call it al-maani’ah (that which protects). In the Book of ALLAH it is a surah which, whoever recites it every night has done very well. "
