The word(s) "therefore" appears 36 time(s) in 36 verse(s) in Quran in Mohsin Khan translation.

(21) Say (O Muhammad صلى الله عليه وسلم): "I am only a human being like you. It is revealed to me that your Ilah (God) is One Ilah (God - Allah), therefore take Straight Path to Him (with true Faith - Islamic Monotheism) and obedience to Him, and seek forgiveness of Him. And woe to Al-Mushrikun (the polytheists, idolaters, disbelievers in the Oneness of Allah).

(22) And he ['Îsa (Jesus), son of Maryam (Mary)] shall be a known sign for (the coming of) the Hour (Day of Resurrection) [i.e. 'Isa's (Jesus) descent on the earth]. therefore have no doubt concerning it (i.e. the Day of Resurrection). And follow Me (Allah) (i.e. be obedient to Allah and do what He orders you to do, O mankind)! This is the Straight Path (of Islamic Monotheism, leading to Allah and to His Paradise).

(23) And when 'Îsa (Jesus) came with (Our) clear Proofs, he said: "I have come to you with Al-Hikmah (Prophethood), and in order to make clear to you some of the (points) in which you differ. therefore fear Allah and obey me.

(24) therefore be patient (O Muhammad صلى الله عليه وسلم) as did the Messengers of strong will and be in no haste about them (disbelievers). On the Day when they will see that (torment) with which they are promised (i.e. threatened, it will be) as if they had not stayed more than an hour in a single day. (O mankind! this Qur'an is sufficient as) a clear Message (or proclamation to save yourself from destruction). But shall any be destroyed except the people who are Al-Fasiqun (the rebellious against Allah's Command, the disobedient to Allah)?

(25) therefore, remind (mankind of Islamic Monotheism, O Muhammad صلى الله عليه وسلم). By the Grace of Allah, you are neither a soothsayer, nor a madman.

(26) therefore withdraw (O Muhammad صلى الله عليه وسلم) from him who turns away from Our Reminder (this Qur'an) and desires nothing but the life of this world.

(27) That is because they believed, and then disbelieved; therefore their hearts are sealed, so they understand not.

(28) therefore, believe in Allah and His Messenger (Muhammad صلى الله عليه وسلم) and in the Light (this Qur'an) which We have sent down. And Allah is All-Aware of what you do.

(29) Allah! La ilaha illa Huwa (none has the right to be worshipped but He). And in Allah (Alone) therefore, let the believers put their trust.

(30) O you who believe! Verily, among your wives and your children there are enemies for you (who may stop you from the obedience of Allah); therefore beware of them! But if you pardon (them) and overlook, and forgive (their faults), then verily Allah is Oft-Forgiving, Most Merciful.
