God says -
….who remember God when they stand, when they sit, and when they lie down to sleep… Q.3:191
And never say about anything, “Behold I shall do this tomorrow,” without [adding], “if God so wills,” And if though shouldst forget [thyself at the time, and become aware of it later], call thy Sustainer to mind and say: “I pray that my Sustainer guide me, even closer than this, to a consciousness of what is right!” Q.18:23/24
But as for anyone who chooses to remain blind to the remembrance of the Most Gracious, to him We assign an [enduring] evil impulse, to become his other self: whereupon, behold, these [evil impulses] bar all such from the path [of truth], making them think that they are guided aright! Q.43:36/37
Prophet said -
1. “Phrases most liked by God are four : SUBHANALLAHI (glory be to God), WALHAMDU LIL LAHI (all praise is for God), WALA ILAHA ILLALLAHU (there is no deity except God), WALLAAHU AKBAR (God is the greatest).” -- Hadis: Bukhari and Muslim. Narrator: Samorah-b-Jandab.
2. “Two phrases are light on tongue but will carry much weight on the Day of Judgment (and) are dear to the Merciful : SUBHANAL LAHI WA BIHAMDIHI (glory be to God and I begin with His praise), WA SUBHANAL LAHIL AZEEM (and glory be to Almighty God).” -- Hadis: Bukhari and Muslim. Narrator: Abu Hurairah.
3. “Let me direct you to a treasure out of the treasures of paradise. Recite : LA HAULA WALA QUWWATA ILLA BILLAH (there is no might and no power but that of God).” -- Hadis: Bukhari and Muslim. Narrator: Abu Musa Al Ash’ari.
