It is narrated from Hazrat Bara’ (may Allah be pleased with him) that a man was reciting Surah Al-Kahf, and there was an animal (a horse) tied in the house. Suddenly, it started to become restless. The man looked and saw that there was a cloud or canopy that had covered him. He mentioned this to the Noble Prophet (peace and blessings be upon him), so the Noble Prophet (peace and blessings be upon him) said, "O so-and-so! Keep reciting, for that was tranquility (sakinah) which descends at the time of the recitation of the Noble Qur’an."
