Tranquility from reciting the Qur’an
Al-Bara’ bin ‘Azib (radi Allahu anhu) reported: A man was reciting Surat Al-Kahf, and a horse was tied with two ropes beside him. As he was reciting, a cloud overshadowed him, and as it began to come nearer and nearer, the horse began to trample violently. The man came to the Messenger of Allah (sal Allahu alaihi wa sallam) in the morning and mentioned the incident to him. He (sal Allahu alaihi wa sallam) said, “That was tranquility which descended as a result of the recitation of the Qur’an.”
[Sahih Al-Bukhari and Muslim]
This Hadith brings out two points.
Firstly, the excellence of Surat Al-Kahf (The Cave, Surah No. 18).
Secondly, the descending of tranquility from Allah on the pious persons. The appearance of a cloud for the tranquility of heart on the recitation of the Qur’an is a supernatural event (miracle) to which a pious man does not make any contribution. It entirely depends on the Will of Allah.
And Allah knows best!
