The word(s) "since" appears 25 time(s) in 25 verse(s) in Quran in Mohsin Khan translation.

(11) To Him belongs all that is in the heavens and (all that is in) the earth and Ad-Din Wasiba is His [(i.e. perpetual sincere obedience to Allah is obligatory). None has the right to be worshipped but Allah)]. Will you then fear any other than Allah?

(12) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(13) Why did they not produce four witnesses? since they (the slanderers) have not produced witnesses! Then with Allah they are the liars.

(14) And when harm touches men, they cry sincerely only to their Lord (Allah), turning to Him in repentance; but when He gives them a taste of His Mercy, behold, a party of them associates partners in worship with their Lord.

(15) Verily We have sent down the Book to you (O Muhammad صلى الله عليه وسلم) in truth: So worship Allah (Alone) by doing religious deeds sincerely for Allah's sake only.

(16) Say (O Muhammad صلى الله عليه وسلم): "Verily I am commanded to worship Allah (Alone) by obeying Him and doing religious deeds sincerely for His sake only.

(17) Say (O Muhammad صلى الله عليه وسلم): "Allah Alone I worship by doing religious deeds sincerely for His sake only (and not to show off, and not to set up rivals with Him in worship.)"

(18) So, call you (O Muhammad صلى الله عليه وسلم and the believers) upon (or invoke) Allah making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allah's sake only and not to show off and not to set up rivals with Him in worship), however much the disbelievers (in the Oneness of Allah) may hate (it).

(19) He is the Ever Living, La ilaha illa Huwa (none has the right to be worshipped but He); so invoke Him making your worship pure for Him Alone (by worshipping Him Alone, and none else, and by doing righteous deeds sincerely for Allah's sake only, and not to show off, and not setting up rivals with Him in worship). All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists).

(20) Say (O Muhammad صلى الله عليه وسلم): "I have been forbidden to worship those whom you worship besides Allah, since there have come to me evidence from my Lord; and I am commanded to submit (in Islam) to the Lord of the 'Alamin (mankind, jinn and all that exists).
