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

(1) When thou didst say unto the believers: Is it not sufficient for you that your Lord should support you with three thousand angels sent down (to your help)?

(2) Those unto whom men said: Lo! the people have gathered against you, therefor fear them. (The threat of danger) but increased the faith of them and they cried: Allah is sufficient for us! Most Excellent is He in Whom we trust!

(3) Allah knoweth best (who are) your enemies. Allah is sufficient as a Guardian, and Allah is sufficient as a Supporter.

(4) And of them were (some) who believed therein and of them were (some) who turned away from it. Hell is sufficient for (their) burning.

(5) Whatever of good befalleth thee (O man) it is from Allah, and whatever of ill befalleth thee it is from thyself. We have sent thee (Muhammad) as a messenger unto mankind and Allah is sufficient as Witness.

(6) And they say: (It is) obedience; but when they have gone forth from thee a party of them spend the night in planning other than what thou sayest. Allah recordeth what they plan by night. So oppose them and put thy trust in Allah. Allah is sufficient as Trustee.

(7) Unto Allah belongeth whatsoever is in the heavens and whatsoever is in the earth. And Allah is sufficient as Defender.

(8) But Allah (Himself) testifieth concerning that which He hath revealeth unto thee; in His knowledge hath He revealed it; and the angels also testify. And Allah is sufficient Witness.

(9) O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not "Three" - Cease! (it is) better for you! - Allah is only One Allah. Far is it removed from His Transcendent Majesty that He should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.

(10) And if they would deceive thee, then lo! Allah is sufficient for thee. He it is Who supporteth thee with His help and with the believers,
