The word(s) "muslim" appears 16 time(s) in 15 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the cult of your father Abraham. It is He Who has named you muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah! He is your Protector - the Best to protect and the Best to help!

(12) And when it is recited to them, they say: "We believe therein, for it is the Truth from our Lord: indeed we have been muslims (bowing to Allah's Will) from before this.

(13) For muslim men and women,- for believing men and women, for devout men and women, for true men and women, for men and women who are patient and constant, for men and women who humble themselves, for men and women who give in Charity, for men and women who fast (and deny themselves), for men and women who guard their chastity, and for men and women who engage much in Allah's praise,- for them has Allah prepared forgiveness and great reward.

(14) But We found not there any just (muslim) persons except in one house:

(15) Whether ye cut down (O ye muslim!) The tender palm-trees, or ye left them standing on their roots, it was by leave of Allah, and in order that He might cover with shame the rebellious transgresses.
