The word(s) "beware" appears 12 time(s) in 12 verse(s) in Quran in Muhammad Pickthal translation.

(1) There is no sin for you in that which ye proclaim or hide in your minds concerning your troth with women. Allah knoweth that ye will remember them. But plight not your troth with women except by uttering a recognised form of words. And do not consummate the marriage until (the term) prescribed is run. Know that Allah knoweth what is in your minds, so beware of Him; and know that Allah is Forgiving, Clement.

(2) Let not the believers take disbelievers for their friends in preference to believers. Whoso doeth that hath no connection with Allah unless (it be) that ye but guard yourselves against them, taking (as it were) security. Allah biddeth you beware (only) of Himself. Unto Allah is the journeying.

(3) On the Day when every soul will find itself confronted with all that it hath done of good and all that it hath done of evil (every soul) will long that there might be a mighty space of distance between it and that (evil). Allah biddeth you beware of Him. And Allah is Full of Pity for (His) bondmen.

(4) O Messenger! Let not them grieve thee who vie one with another in the race to disbelief, of such as say with their mouths: "We believe," but their hearts believe not, and of the Jews: listeners for the sake of falsehood, listeners on behalf of other folk who come not unto thee, changing words from their context and saying: If this be given unto you, receive it, but if this be not given unto you, then beware! He whom Allah doometh unto sin, thou (by thine efforts) wilt avail him naught against Allah. Those are they for whom the Will of Allah is that He cleanse not their hearts. Theirs in the world will be ignominy, and in the Hereafter an awful doom;

(5) So judge between them by that which Allah hath revealed, and follow not their desires, but beware of them lest they seduce thee from some part of that which Allah hath revealed unto thee. And if they turn away, then know that Allah's Will is to smite them for some sin of theirs. Lo! many of mankind are evil-livers.

(6) Obey Allah and obey the messenger, and beware! But if ye turn away, then know that the duty of Our messenger is only plain conveyance (of the message).

(7) And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.

(8) And his people came unto him, running towards him - and before then they used to commit abominations - He said: O my people! Here are my daughters! They are purer for you. beware of Allah, and degrade me not in (the person of) my guests. Is there not among you any upright man?

(9) Make not the calling of the messenger among you as your calling one of another. Allah knoweth those of you who steal away, hiding themselves. And let those who conspire to evade orders beware lest grief or painful punishment befall them.

(10) When it is said unto them: beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless).
