The word(s) "truer" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Allah! There is no god but He: of a surety He will gather you together against the Day of Judgment, about which there is no doubt. And whose word can be truer than Allah's?

(2) But those who believe and do deeds of righteousness,- we shall soon admit them to gardens, with rivers flowing beneath,-to dwell therein for ever. Allah's promise is the truth, and whose word can be truer than Allah's?

(3) But if it gets known that these two were guilty of the sin (of perjury), let two others stand forth in their places,- nearest in kin from among those who claim a lawful right: let them swear by Allah: "We affirm that our witness is truer than that of those two, and that we have not trespassed (beyond the truth): if we did, behold! the wrong be upon us!"
