The word(s) "debar" appears 15 time(s) in 14 verse(s) in Quran in Muhammad Pickthal translation.

(11) I found her and her people worshipping the sun instead of Allah; and Satan maketh their works fairseeming unto them, and debarreth them from the way (of Truth), so that they go not aright;

(12) And (the tribes of) A'ad and Thamud! (Their fate) is manifest unto you from their (ruined and deserted) dwellings. Satan made their deeds seem fair unto them and so debarred them from the Way, though they were keen observers.

(13) The roads of the heavens, and may look upon the god of Moses, though verily I think him a liar. Thus was the evil that he did made fairseeming unto Pharaoh, and he was debarred from the (right) way. The plot of Pharaoh ended but in ruin.

(14) These it was who disbelieved and debarred you from the Inviolable Place of Worship, and debarred the offering from reaching its goal. And if it had not been for believing men and believing women, whom ye know not - lest ye should tread them under foot and thus incur guilt for them unknowingly; that Allah might bring into His mercy whom He will - If (the believers and the disbelievers) had been clearly separated We verily had punished those of them who disbelieved with painful punishment.
