Mukhtasar Muslim

Sayyiduna Bara’ (may Allah be pleased with him) reports that a man was reciting Surah Al-Kahf and nearby, a horse was tied with two long ropes. Then a cloud came over him, which began to circle and draw near, and seeing this, his horse started to shy away. When morning came, the man went to the Prophet (peace and blessings be upon him) and mentioned what had happened during the night. The Prophet (peace and blessings be upon him) said, “That was tranquility (sakinah) which descended due to the blessing of the Qur’an.”
