Grand Qur'aan
The Infinitely Reliable Book-It is the Guarantor and Sustainer of The Life, tranquility and happiness. Listen it, learn it, and know and understand it since it has been made easy and self explanatory. Thereupon, act accordingly what it commands and refrain from that which it prohibits.
O you who declare to have accepted! You people make yourselves consciously answer/respond to Allah, the Exalted and answer/respond affirmatively to the Messenger [Sal'lallaa'hoalaih'wa'salam, by carefully and attentively listening] when he calls you people towards that-Grand Qur'aan which will give you people life [in the Hereafter eternally comfortable and enjoyable-let us say responding "We have listened the Grand Qur'aan and we have affectionately and wholeheartedly accepted it, O you the Messenger Sal'lallaa'hoalaih'wa'salam"]
Realize it that the life of this lowly world is nothing except like short lived theatrical play and amusement, and know the certain fact that the Home of the Hereafter is that which is truly The living Life. [29:64]
Had they but known/tried to analyze it. [29:64]
