Translation of the verse 191 from Surah al-‘Imran : Number of verses 200 - - page 75 - Part 4.
Those who remember Allah (always, and in prayers) standing, sitting, and lying down on their sides, and think deeply about the creation of the heavens and the earth, (saying): "Our Lord! You have not created (all) this without purpose, glory to You! (Exalted be You above all that they associate with You as partners). Give us salvation from the torment of the Fire.
Who remember Allah while standing or sitting or [lying] on their sides and give thought to the creation of the heavens and the earth, [saying], "Our Lord, You did not create this aimlessly; exalted are You [above such a thing]; then protect us from the punishment of the Fire.
(3:191) those who remember Allah while standing, sitting or (reclining) on their backs, and reflect in the creation of the heavens and the earth, *135 (saying): 'Our Lord! You have not created this in vain. Glory to You! Save us, then, from the chastisement of the Fire. *136
*135). This means that with the help of those signs one can easily arrive at the Truth, provided one is not indifferent to God and looks at the phenomenon of the universe thoughtfully.
*136). When people look carefully at the order of the universe, it becomes clear to them that it is an order permeated by wisdom and intelligent purpose. It is altogether inconsistent with wisdom that the man endowed with moral consciousness and freedom of choice, the man gifted with reason and discretion, should not be held answerable for his deeds. This kind of reflection leads people to develop a strong conviction that the After-life is a reality. Thanks to this conviction, they begin to seek God's refuge from His punishment.
