وَلَوْ تَرَىٰٓ إِذِ ٱلْمُجْرِمُونَ نَاكِسُوا۟ رُءُوسِهِمْ عِندَ رَبِّهِمْ رَبَّنَآ أَبْصَرْنَا وَسَمِعْنَا فَٱرْجِعْنَا نَعْمَلْ صَٰلِحًا إِنَّا مُوقِنُونَ
Couldst thou but see when the guilty hang their heads before their Lord, (and say): Our Lord! We have now seen and heard, so send us back; we will do right, now we are sure.

Sahih al-Bukhari
Virtues of the Qur'an
Chapter: The superiority of Surat Al-Kahf (No.18)
Narrated Al-Bara':
A man was reciting Surat Al-Kahf and his horse was tied with two ropes beside him. A cloud came down and spread over that man, and it kept on coming closer and closer to him till his horse started jumping (as if afraid of something). When it was morning, the man came to the Prophet, and told him of that experience. The Prophet (ﷺ) said, "That was As-Sakina (tranquility) which descended because of (the recitation of) the Qur'an."
