The word(s) "regard" appears 52 time(s) in 45 verse(s) in Quran in Mohsin Khan translation.

(41) We will show them Our Signs in the universe, and in their own selves, until it becomes manifest to them that this (the Qur'an) is the truth. Is it not sufficient in regard to your Lord that He is a Witness over all things?

(42) And those who dispute (polytheists with Our Messenger Muhammad صلى الله عليه و سلم) as regards Our Ayat (proofs, signs, verses, etc. of Islamic Monotheism) may know that there is no place of refuge for them (from Allah's punishment) [Tafsir At-Tabari].

(43) They regard as favour to you (O Muhammad صلى الله عليه وسلم) that they have embraced Islam. Say: "Count not your Islam as a favour to me. Nay, but Allah has conferred a favour upon you that He has guided you to the Faith if you indeed are true.

(44) It is only as regards those who fought against you on account of religion, and have driven you out of your homes, and helped to drive you out, that Allah forbids you to befriend them. And whosoever will befriend them, then such are the Zalimun (wrong-doers - those who disobey Allah).

(45) And We have set none but angels as guardians of the Fire. And We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and Christians) may arrive at a certainty [that this Qur'an is the truth as it agrees with their Books regarding the number (19) which is written in the Taurat (Torah) and the Injeel (Gospel)] and that the believers may increase in Faith (as this Qur'an is the truth), and that no doubt may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example ?" Thus Allah leads astray whom He wills and guides whom He wills. And none can know the hosts of your Lord but He. And this (Hell) is nothing else than a (warning) reminder to mankind.
