The word(s) "yusuf" appears 45 time(s) in 40 verse(s) in Quran in Mohsin Khan translation.

(31) So, when they despaired of him, they held a conference in private. The eldest among them said: "Know you not that your father did take an oath from you in Allah's Name, and before this you did fail in your duty with yusuf (Joseph)? Therefore I will not leave this land until my father permits me, or Allah decides my case (by releasing Benjamin) and He is the Best of the judges.

(32) And he turned away from them and said: "Alas, my grief for yusuf (Joseph)!" And he lost his sight because of the sorrow that he was suppressing.

(33) They said: "By Allah! You will never cease remembering yusuf (Joseph) until you become weak with old age, or until you be of the dead."

(34) "O my sons! Go you and enquire about yusuf (Joseph) and his brother, and never give up hope of Allah's Mercy. Certainly no one despairs of Allah's Mercy, except the people who disbelieve."

(35) Then, when they entered unto him [yusuf (Joseph)], they said: "O ruler of the land! A hard time has hit us and our family, and we have brought but poor capital, so pay us full measure and be charitable to us. Truly, Allah does reward the charitable."

(36) He said: "Do you know what you did with yusuf (Joseph) and his brother, when you were ignorant?"

(37) They said: "Are you indeed yusuf (Joseph)?" He said: "I am yusuf (Joseph), and this is my brother (Benjamin). Allah has indeed been gracious to us. Verily, he who fears Allah with obedience to Him (by abstaining from sins and evil deeds, and by performing righteous good deeds), and is patient, then surely, Allah makes not the reward of the Muhsinun (good-doers - see V.2:112) to be lost."

(38) And when the caravan departed, their father said: "I do indeed feel the smell of yusuf (Joseph), if only you think me not a dotard (a person who has weakness of mind because of old age)."

(39) Then, when they came in before yusuf (Joseph), he took his parents to himself and said: "Enter Egypt, if Allah wills, in security."

(40) And indeed yusuf (Joseph) did come to you, in times gone by, with clear signs, but you ceased not to doubt in that which he did bring to you: till when he died you said: "No Messenger will Allah send after him." Thus Allah leaves astray him who is a Musrif (a polytheist, an oppressor, a criminal, sinner who commit great sins) and a Murtab (one who doubts Allah's Warning and His Oneness).
