The word(s) "friend" appears 90 time(s) in 78 verse(s) in Quran in Muhammad Pickthal translation.

(21) And if they turn away, then know that Allah is your Befriender - a Transcendent Patron, a Transcendent Helper!

(22) Lo! those who believed and left their homes and strove with their wealth and their lives for the cause of Allah, and those who took them in and helped them: these are protecting friends one of another. And those who believed but did not leave their homes, ye have no duty to protect them till they leave their homes; but if they seek help from you in the matter of religion then it is your duty to help (them) except against a folk between whom and you there is a treaty. Allah is Seer of what ye do.

(23) O ye who believe! Choose not your fathers nor your brethren for friends if they take pleasure in disbelief rather than faith. Whoso of you taketh them for friends, such are wrong-doers.

(24) Say: Naught befalleth us save that which Allah hath decreed for us. He is our Protecting friend. In Allah let believers put their trust!

(25) And the believers, men and women, are protecting friends one of another; they enjoin the right and forbid the wrong, and they establish worship and they pay the poor-due, and they obey Allah and His messenger. As for these, Allah will have mercy on them. Lo! Allah is Mighty, Wise.

(26) They swear by Allah that they said nothing (wrong), yet they did say the word of disbelief, and did disbelieve after their Surrender (to Allah). And they purposed that which they could not attain, and they sought revenge only that Allah by His messenger should enrich them of His bounty. If they repent it will be better for them; and if they turn away, Allah will afflict them with a painful doom in the world and the Hereafter, and they have no protecting friend nor helper in the earth.

(27) Lo! Allah! Unto Him belongeth the Sovereignty of the heavens and the earth. He quickeneth and He giveth death. And ye have, instead of Allah, no protecting friend nor helper.

(28) Lo! verily the friends of Allah are (those) on whom fear (cometh) not, nor do they grieve?

(29) Such will not escape in the earth, nor have they any protecting friends beside Allah. For them the torment will be double. They could not bear to hear, and they used not to see.

(30) And incline not toward those who do wrong lest the Fire touch you, and ye have no protecting friends against Allah, and afterward ye would not be helped.
