The word(s) "truer" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And (as for) those who believe and do good, We will make them enter into gardens beneath which rivers flow, to abide therein for ever; (it is) a promise of Allah, true (indeed), and who is truer of word than Allah?

(2) Then if it becomes known that they both have been guilty of a sin, two others shall stand up in their place from among those who have a claim against them, the two nearest in kin; so they two should swear by Allah: Certainly our testimony is truer than the testimony of those two, and we have not exceeded the limit, for then most surely we should be of the unjust.
