The word(s) "sooth" appears 18 time(s) in 18 verse(s) in Quran in Muhammad Pickthal translation.

(1) He it is Who hath revealed unto thee (Muhammad) the Scripture wherein are clear revelations - they are the substance of the Book - and others (which are) allegorical. But those in whose hearts is doubt pursue, forsooth, that which is allegorical seeking (to cause) dissension by seeking to explain it. None knoweth its explanation save Allah. And those who are of sound instruction say: We believe therein; the whole is from our Lord; but only men of understanding really heed.

(2) Verily Allah heard the saying of those who said, (when asked for contributions to the war): "Allah, forsooth, is poor, and we are rich!" We shall record their saying with their slaying of the prophets wrongfully and We shall say: Taste ye the punishment of burning!

(3) Say (O Muhammad): What thing is of most weight in testimony? Say: Allah is Witness between me and you. And this Qur'an hath been inspired in me, that I may warn therewith you and whomsoever it may reach. Do ye in sooth bear witness that there are gods beside Allah? Say: I bear no such witness. Say: He is only One Allah. Lo! I am innocent of that which ye associate (with Him).

(4) Lest ye should say: The Scripture was revealed only to two sects before us, and we in sooth were unaware of what they read;

(5) And the answer of his people was only that they said (one to another): Turn them out of your township. They are folk, forsooth, who keep pure.

(6) And if thou wonderest, then wondrous is their saying: When we are dust, are we then forsooth (to be raised) in a new creation? Such are they who disbelieve in their Lord; such have carcans on their necks; such are rightful owners of the Fire, they will abide therein.

(7) And they say: When we are bones and fragments, shall we forsooth, be raised up as a new creation?

(8) That is their reward because they disbelieved Our revelations and said: When we are bones and fragments shall we, forsooth, be raised up as a new creation?

(9) And man saith: When I am dead, shall I forsooth be brought forth alive?

(10) They say: When we are dead and have become (mere) dust and bones, shall we then, forsooth, be raised again?
