The word(s) "truer" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) Allah! La ilaha illa Huwa (none has the right to be worshipped but He). Surely, He will gather you together on the Day of Resurrection about which there is no doubt. And who is truer in statement than Allah?

(2) But those who believe (in the Oneness of Allah - Islamic Monotheism) and do deeds of righteousness, We shall admit them to the Gardens under which rivers flow (i.e. in Paradise) to dwell therein forever. Allah's Promise is the Truth; and whose words can be truer than those of Allah? (Of course, none).

(3) If then it gets known that these two had been guilty of sin, let two others stand forth in their places, nearest in kin from among those who claim a lawful right. Let them swear by Allah (saying): "We affirm that our testimony is truer than that of both of them, and that we have not trespassed (the truth), for then indeed we should be of the wrong-doers."

(4) Verily, Allah has purchased of the believers their lives and their properties for (the price) that theirs shall be the Paradise. They fight in Allah's Cause, so they kill (others) and are killed. It is a promise in truth which is binding on Him in the Taurat (Torah) and the Injeel (Gospel) and the Qur'an. And who is truer to his covenant than Allah? Then rejoice in the bargain which you have concluded. That is the supreme success.
