The Hour when Supplication is answered and the Recitation of Surah Al-Kahf on Friday
Question :
Is there any superiority in reciting Surah Al-Kahf on Friday? And it correct that the hour when supplication is answered is on Friday between the first and second Athan?
Question :
A Hadith has been narrated concerning the virtue of reciting Surah Al-Kahf on Friday, which was mentioned by Ibn Kathir in the beginning of his Tafsir of it, but there is some weakness in it. Many of the scholars of Fiqh have recommended its recitation and mentioned it in their books. As for the hour when supplication is answered on Friday, it has been authentically reported in the Hadiths that it is the last hour after 'Asr and it has also been reported that it is at the time of the Friday prayer, from the time when the Imam sits at the pulpit, until the end of the prayer. There are many other sayings concerning it - but the best thing for the Muslim to do is to strive to make supplications throughout the whole day, in the hope that he will catch it.
