All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
There is a great reward for reciting the Quran. It is better for a person to arrange a schedule to recite the whole Quran, as regards specifying a specific chapter at a particular time, then there must be textual evidence for this. There is evidence that chapter 18 [Al-Kahf] should be recited on a Friday, but there is no evidence –as far as we know –for reciting Yaa Seen [chapter 36] precisely on a Friday. Therefore, in our view, you should continue the recitation of the entire Quran instead of reciting this chapter only.
For more benefit on the virtue of reciting chapter Al-Kahf and some other chapters, please refer to Fatwa 84014, and to Fatwa 86828 on reciting the Quran on behalf of the dead.
Allaah Knows best.
