Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with him) reports that a man recited Surah Al-Kahf, and there was a horse tied in his house which began to get restless. So he ended his prayer (because he was reciting during prayer) and saw that there was a cloud that had covered the whole house. He mentioned this to the Prophet Muhammad (peace and blessings be upon him), so he (peace be upon him) said: “O so-and-so! Continue reciting the Qur’an. This is tranquility which descended because of the recitation of the Qur’an.”
