The word(s) "now" appears 868 time(s) in 728 verse(s) in Quran in Mohsin Khan translation.

(511) But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not; but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and in obedience. Then to Me will be your return, and I shall tell you what you used to do.

(512) See you not (O men) that Allah has subjected for you whatsoever is in the heavens and whatsoever is in the earth, and has completed and perfected His Graces upon you, (both) apparent (i.e. Islamic Monotheism, and the lawful pleasures of this world, including health, good looks, etc.) and hidden [i.e. One's Faith in Allah (of Islamic Monotheism) knowledge, wisdom, guidance for doing righteous deeds, and also the pleasures and delights of the Hereafter in Paradise]? Yet of mankind is he who disputes about Allah without knowledge or guidance or a Book giving light!

(513) And whoever disbelieves, let not his disbelief grieve you (O Muhammad صلى الله عليه وسلم). To Us is their return, and We shall inform them what they have done. Verily, Allah is the All-Knower of what is in the breasts (of men).

(514) And if you (O Muhammad صلى الله عليه وسلم) ask them: "Who has created the heavens and the earth," they will certainly say: "Allah." Say: "All the praises and thanks be to Allah!" But most of them know not.

(515) Verily Allah, with Him (Alone) is the knowledge of the Hour, He sends down the rain, and knows that which is in the wombs. No person knows what he will earn tomorrow, and no person knows in what land he will die. Verily, Allah is All-Knower, All-Aware (of things).

(516) Alif-Lam-Mim. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings].

(517) That is He: the All-Knower of the unseen and the seen, the All-Mighty, the Most Merciful.

(518) And if you only could see when the Mujrimun (criminals, disbelievers, polytheists, sinners) shall hang their heads before their Lord (saying): "Our Lord! We have now seen and heard, so send us back (to the world), that we will do righteous good deeds. Verily! We now believe with certainty."

(519) No person knows what is kept hidden for them of joy as a reward for what they used to do.

(520) O Prophet (Muhammad صلى الله عليه وسلم)! Keep your duty to Allah, and obey not the disbelievers and the hypocrites (i.e., do not follow their advice). Verily, Allah is Ever All-Knower, All-Wise.
