Benefits of Surah al Kahf (18)

The Prophet (salAllahu alayhi wasalam) said,
‘Whoever recited Surah al Kahf in the same
manner in which it was revealed, it will serve for
him as a light on the Day of Judgement, from his
domicile to Makkah. And whoever recited the last
ten verses, and it happens that the Dajjal should
appear after that, Dajjal will not be empowered
over him’.
[Hakim 1/564 & Dhahabi]
Abu’d-Darda’ reported that the Messenger of
Allah (salAllahu alayhi wasalam) said, “Anyone
who memorises ten ayats from the beginning of
Surat al-Kahf (18) will be protected from the
Dajjal.”
[Muslim, Riyad as-Salihin by Imam an-Nawawi
183 #1012]
One variant has, “from the end of Surat al-Kahf.”
The Prophet (salAllahu alayhi wasalam) said,
‘Whoever recited Surah al Kahf on a Friday, Allah
will kindle for him abundant light to brightly
illuminate the period between the two Fridays
(the Friday on which the recitation was made and
the next Friday)’
[Hakim 2/367, Mishkat al-Masabih #2175,
however Baihaqi disagreed with it’s authenticity
in Sahih Al Jami 2/1104]
Narrated Al-Bara’bin Azib: A man was reciting
Surah 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 said, “That was As-
Sakina (tranquility) which descended because of
(the recitation of) the Qur’an.”
[Sahih al-Bukhari 6:61 #531, at-Tirmidhi 2810/A]
