The word(s) "contumacy" appears 7 time(s) in 7 verse(s) in Quran in Muhammad Pickthal translation.

(1) Allah (Himself) doth mock them, leaving them to wander blindly on in their contumacy.

(2) The Jews say: Allah's hand is fettered. Their hands are fettered and they are accursed for saying so. Nay, but both His hands are spread out wide in bounty. He bestoweth as He will. That which hath been revealed unto thee from thy Lord is certain to increase the contumacy and disbelief of many of them, and We have cast among them enmity and hatred till the Day of Resurrection. As often as they light a fire for war, Allah extinguisheth it. Their effort is for corruption in the land, and Allah loveth not corrupters.

(3) Say O People of the Scripture! Ye have naught (of guidance) till ye observe the Torah and the Gospel and that which was revealed unto you from your Lord. That which is revealed unto thee (Muhammad) from thy Lord is certain to increase the contumacy and disbelief of many of them. But grieve not for the disbelieving folk.

(4) We confound their hearts and their eyes. As they believed not therein at the first, We let them wander blindly on in their contumacy.

(5) Those whom Allah sendeth astray, there is no guide for them. He leaveth them to wander blindly on in their contumacy.

(6) If Allah were to hasten on for men the ill (that they have earned) as they would hasten on the good, their respite would already have expired. But We suffer those who look not for the meeting with Us to wander blindly on in their contumacy.

(7) Though We had mercy on them and relieved them of the harm afflicting them, they still would wander blindly on in their contumacy.
