Ibn Mas’ood (Radiallahu Anhu) reports that Rasulullah Sallallahu Alayhi Wasallam  said, “Whoever reads surah AI-Waaqi’ah every night, starvation shall never afflict him.”  

Ibn Mas’ood (Radiallahu Anhu) used-to command his daughters to recite this surah every night.  

The virtues of surah Al Waaqi’ah are also reported in many ahadith.   

There is a riwaayat to the effect that whoever reads surahs Al-Hadeed, AI-Waaqi’ah and Ar-Rahmaan, is reckoned amongst the dwellers of Jannat-ul­ Firdaus (the highest level of Paradise).   

In another hadith, it is stated that surah AI-Waaqi’ah, is surah Al-Ghinaa (Prosperity). Read it and teach it to your children.   

Another riwaayat says: “Teach it to your wives.”  Hadhrat ‘Aa’-ishah (Radiallahu anha) is reported to have emphasized its reading. But it is low mentality on our part to read it only for sake of petty· worldly gain. If instead, it is read for the contentment of the heart and for the sake of the next world, then worldly gains will come to us without asking.
