The word(s) "warrant" appears 25 time(s) in 25 verse(s) in Quran in Muhammad Pickthal translation.

(11) Or thou cause the heaven to fall upon us piecemeal, as thou hast pretended, or bring Allah and the angels as a warrant;

(12) These, our people, have chosen (other) gods beside Him though they bring no clear warrant (vouchsafed) to them. And who doth greater wrong than he who inventeth a lie concerning Allah?

(13) And they worship instead of Allah that for which He hath sent down no warrant, and that whereof they have no knowledge. For evil-doers there is no helper.

(14) Then We sent Moses and his brother Aaron with Our tokens and a clear warrant

(15) Or have We revealed unto them any warrant which speaketh of that which they associate with Him?

(16) And he had no warrant whatsoever against them, save that We would know him who believeth in the Hereafter from him who is in doubt thereof; and thy Lord (O Muhammad) taketh note of all things.

(17) Or have ye a clear warrant?

(18) And verily We sent Moses with Our revelations and a clear warrant

(19) Those who wrangle concerning the revelations of Allah without any warrant that hath come unto them, it is greatly hateful in the sight of Allah and in the sight of those who believe. Thus doth Allah print on every arrogant, disdainful heart.

(20) Lo! those who wrangle concerning the revelations of Allah without a warrant having come unto them, there is naught else in their breasts save pride which they will never attain. So take thou refuge in Allah. Lo! He, only He, is the Hearer, the Seer.
