The word(s) "friends" appears 42 time(s) in 36 verse(s) in Quran in Muhammad Pickthal translation.

(11) O Children of Adam! Let not Satan seduce you as he caused your (first) parents to go forth from the Garden and tore off from them their robe (of innocence) that he might manifest their shame to them. Lo! he seeth you, he and his tribe, from whence ye see him not. Lo! We have made the devils protecting friends for those who believe not.

(12) 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.

(13) 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.

(14) 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.

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

(16) 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.

(17) 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.

(18) They said: O our father! Why wilt thou not trust us with Joseph, when lo! we are good friends to him?

(19) And he whom Allah guideth, he is led aright; while, as for him whom He sendeth astray, for them thou wilt find no protecting friends beside Him, and We shall assemble them on the Day of Resurrection on their faces, blind, dumb and deaf; their habitation will be hell; whenever it abateth, We increase the flame for them.

(20) And (remember) when We said unto the angels: Fall prostrate before Adam, and they fell prostrate, all save Iblis. He was of the jinn, so he rebelled against his Lord's command. Will ye choose him and his seed for your protecting friends instead of Me, when they are an enemy unto you? Calamitous is the exchange for evil-doers.
