Q. Is there a Hadith that stresses the importance of reading Surah 36, Yaseen, in the morning, and surahs 55, Al-Rahman, 56, Al-Waqi’ah and 67, Al-Mulk in the evening, on a daily basis?
Etouch
A. I am not aware of a Hadith or a group of Hadiths that makes such a recommendation which specifically mentions these four surahs. The Prophet has recommended reading certain surahs frequently, and these four surahs are among them. For example, he is quoted to have said that reading Surah Yaseen ensures the fulfillment of the purpose for which it is read. Such reports, however, are often rather suspect on authenticity. Having said that, I stress that reading the Qur’an is a highly rewarding act of worship which is also generously rewarded by God Almighty.
