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

(41) Do the disbelievers reckon that they can choose My bondmen as protecting friends beside Me? Lo! We have prepared hell as a welcome for the disbelievers.

(42) For him it is decreed that whoso taketh him for friend, he verily will mislead him and will guide him to the punishment of the Flame.

(43) He calleth unto him whose harm is nearer than his benefit; verily an evil patron and verily an evil friend!

(44) And strive for Allah with the endeavour which is His right. He hath chosen you and hath not laid upon you in religion any hardship; the faith of your father Abraham (is yours). He hath named you Muslims of old time and in this (Scripture), that the messenger may be a witness against you, and that ye may be witnesses against mankind. So establish worship, pay the poor-due, and hold fast to Allah. He is your Protecting friend. A blessed Patron and a blessed Helper!

(45) No blame is there upon the blind nor any blame upon the lame nor any blame upon the sick nor on yourselves if ye eat from your houses, or the houses of your fathers, or the houses of your mothers, or the houses of your brothers, or the houses of your sisters, or the houses of your fathers' brothers, or the houses of your fathers' sisters, or the houses of your mothers' brothers, or the houses of your mothers' sisters, or (from that) whereof ye hold the keys, or (from the house) of a friend. No sin shall it be for you whether ye eat together or apart. But when ye enter houses, salute one another with a greeting from Allah, blessed and sweet. Thus Allah maketh clear His revelations for you, that haply ye may understand.

(46) They will say: Be Thou Glorified! it was not for us to choose any protecting friends beside thee; but Thou didst give them and their fathers ease till they forgot the warning and became lost folk.

(47) Alas for me! Ah, would that I had never taken such an one for friend!

(48) Nor any loving friend.

(49) They said: Swear one to another by Allah that we verily will attack him and his household by night, and afterward we will surely say unto his friend: We witnessed not the destruction of his household. And lo! we are truthtellers.

(50) Ye cannot escape (from Him) in the earth or in the sky, and beside Allah there is for you no friend or helper.
