The word(s) "not" appears 2535 time(s) in 1947 verse(s) in Quran in Mohsin Khan translation.

(131) It is He Who has sent down to you (Muhammad صلى الله عليه وسلم) the Book (this Qur'an). In it are Verses that are entirely clear, they are the foundations of the Book [and those are the Verses of Al-Ahkam (commandments), Al-Fara'id (obligatory duties) and Al-Hudud (legal laws for the punishment of thieves, adulterers)]; and others not entirely clear. So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials), and seeking for its hidden meanings, but none knows its hidden meanings save Allah. And those who are firmly grounded in knowledge say: "We believe in it; the whole of it (clear and unclear Verses) are from our Lord." And none receive admonition except men of understanding. (Tafsir At-Tabari).

(132) (They say): "Our Lord! Let not our hearts deviate (from the truth) after You have guided us, and grant us mercy from You. Truly, You are the Bestower."

(133) Truly, the religion with Allah is Islam. Those who were given the Scripture (Jews and Christians) did not differ except, out of mutual jealousy, after knowledge had come to them. And whoever disbelieves in the Ayat (proofs, evidence, verses, signs, revelations, etc.) of Allah, then surely, Allah is Swift in calling to account.

(134) Have you not seen those who have been given a portion of the Scripture? They are being invited to the Book of Allah to settle their dispute, then a party of them turn away, and they are averse.

(135) This is because they say: "The Fire shall not touch us but for a number of days." And that which they used to invent regarding their religion has deceived them.

(136) How (will it be) when We gather them together on the Day about which there is no doubt (i.e. the Day of Resurrection). And each person will be paid in full what he has earned? And they will not be dealt with unjustly.

(137) Let not the believers take the disbelievers as Auliya (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His punishment) , and to Allah is the final return.

(138) Say (O Muhammad صلى الله عليه وسلم to mankind): "If you (really) love Allah then follow me (i.e. accept Islamic Monotheism, follow the Qur'an and the Sunnah), Allah will love you and forgive you your sins. And Allah is Oft-Forgiving, Most Merciful."

(139) Say (O Muhammad صلى الله عليه وسلم): "Obey Allah and the Messenger (Muhammad صلى الله عليه وسلم)." But if they turn away, then Allah does not like the disbelievers .

(140) Then when she gave birth to her [child Maryam (Mary)], she said: "O my Lord! I have given birth to a female child," - and Allah knew better what she brought forth, - "And the male is not like the female, and I have named her Maryam (Mary), and I seek refuge with You (Allah) for her and for her offspring from Shaitan (Satan), the outcast."
