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

(641) They said: "Even so says your Lord. Verily, He is the All-Wise, the All-Knower."

(642) And verily, for those who do wrong, there is another punishment (i.e. the torment in this world and in their graves) before this; but most of them know not. (Tafsir At-Tabari).

(643) But they have no knowledge thereof. They follow but a guess, and verily, guess is no substitute for the truth.

(644) That is what they could reach of knowledge. Verily, your Lord it is He Who knows best him who goes astray from His Path, and He knows best him who receives guidance.

(645) Those who avoid great sins (See the Qur'an, Verses: 6:152,153) and Al-Fawahish (illegal sexual intercourse) except the small faults, - verily, your Lord is of Vast Forgiveness. He knows you well when He created you from the earth (Adam), and when you were fetuses in your mothers' wombs. So ascribe not purity to yourselves. He knows best him who fears Allah and keeps his duty to Him [i.e. those who are Al-Muttaqun (the pious. See V.2:2)].

(649) The Mujrimun (polytheists, criminals, sinners) will be known by their marks (black faces), and they will be seized by their forelocks and their feet.

(650) "All will surely be gathered together for appointed Meeting of a known Day.
