What is the light a Muslim receives for reciting Surah Al-Kahf on Friday?

Question:

I read the hadith which says a Muslim will receive light on Friday if he recites Surah Al-Kahf. What is this light?

Answer:

In the name of Allah, the Beneficent, the Merciful

Abu Sa’eed Al-Khudri reported: The Prophet, peace and blessings be upon him, said:

مَنْ قَرَأَ سُورَةَ الْكَهْفِ فِي يَوْمِ الْجُمُعَةِ أَضَاءَ لَهُ مِنَ النُّورِ مَا بَيْنَ الْجُمُعَتَيْنِ

Whoever recites Surah Al-Kahf on the day of Friday will have a light for him between this Friday and the next.

Source: Sunan Al-Kubra 5856, Grade: Hasan

The meaning of “light” in this narration is that it is guidance from Allah. Light is a common metaphor for guidance, as in the verse:

وَآتَيْنَاهُ الْإِنجِيلَ فِيهِ هُدًى وَنُورٌ

We gave him the Gospel, in which was guidance and light.

Surah Al-Ma’idah 5:46

In the narration of Abu Hisham, the Prophet, peace and blessings be upon him, said:

مَنْ قَرَأَ سُورَةَ الْكَهْفِ كَمَا أُنْزِلَتْ كَانَتْ لَهُ نُورًا يَوْمَ الْقِيَامَةِ

Whoever recites Surah Al-Kahf as it was revealed will have light on the Day of Resurrection.

According to this narration, the good deed of the recitation of Surah Al-Kahf will appear as light on the Day of Resurrection. This light will protect the Muslim from the horrors of the grave and the Hereafter. This is similar to the narration of Abu Abdullah ibn Burayda, in which the Prophet, peace and blessings be upon him, said:

تَعَلَّمُوا سُورَةَ الْبَقَرَةِ وَآلِ عِمْرَانَ فَإِنَّهُمَا الزَّهْرَاوَانِ يُظِلَّانِ صَاحِبَهُمَا يَوْمَ الْقِيَامَةِ كَأَنَّهُمَا غَمَامَتَانِ أَوْ غَيَايَتَانِ أَوْ فِرْقَانِ مِنْ طَيْرٍ صَوَافَّ

Learn Surah Al-Baqarah and Surah Ali Imran because they are the two bright ones and they shade their people on the Day of Resurrection just as two clouds, two spaces of shade or two lines of birds.

An-Nawawi said:

سُمِّيَتَا الزَّهْرَاوَيْنِ لِنُورِهِمَا وَهِدَايَتِهِمَا وَعَظِيمِ أَجْرِهِمَا

They are called the “two bright ones” because of their light, their guidance, and their tremendous reward.

Therefore, a Muslim who recites Surah Al-Kahf on Friday will receive light from Allah in the form of guidance, whether in this life or in the Hereafter.

Success comes from Allah, and Allah knows best
