The Superiority of Surat-al-Falaq & Surat-an-Nas
Narrated by Aisha (Radhiallaho anha):
Whenever Allah’s Messenger (sallallaahu ‘alaihi wasallam), became sick, he would recite Mu’awwidhat (Surat Al-Falaq and Surat An-Nas) and then blow his breath over his body. When he became seriously ill, I used to recite (these two Suras) and rub his hands over his body hoping for its blessings.
The Superiority of the Quran
Narrated by Abu Musa Al Ashari(Radhiallaho anho):
Allah’s Messenger (sallallaahu ‘alaihi wasallam), said, “The example of him (a believer) who recites the Qur’an is like that of a citron which tastes good and smells good. And he (a believer) who does not recite the Qur’an is like a date which is good in taste but has no smell. And the example of a dissolute wicked person who recites the Qur’an is like the Raihana (sweet basil) which smells good but tastes bitter. And the example of a dissolute wicked person who does not recite the Qur’an is like the colocynth which tastes bitter and has no smell.
