The word(s) "orphans" appears 13 time(s) in 13 verse(s) in Quran in Mohsin Khan translation.

(11) And know that whatever of war-booty that you may gain, verily one-fifth (1/5th) of it is assigned to Allah, and to the Messenger, and to the near relatives [of the Messenger (Muhammad صلى الله عليه وسلم)], (and also) the orphans, Al-Masakin (the poor) and the wayfarer, if you have believed in Allah and in that which We sent down to Our slave (Muhammad صلى الله عليه وسلم) on the Day of criterion (between right and wrong), the Day when the two forces met (the battle of Badr); And Allah is able to do all things.

(12) What Allah gave as booty (Fai') to His Messenger (Muhammad صلى الله عليه وسلم) from the people of the townships - it is for Allah, His Messenger (Muhammad صلى الله عليه وسلم), the kindred (of Messenger Muhammad صلى الله عليه وسلم), the orphans, Al-Masakin (the poor), and the wayfarer, in order that it may not become a fortune used by the rich among you. And whatsoever the Messenger (Muhammad صلى الله عليه وسلم) gives you, take it; and whatsoever he forbids you, abstain (from it). And fear Allah; verily, Allah is Severe in punishment.

(13) Nay! But you treat not the orphans with kindness and generosity (i.e. you neither treat them well, nor give them their exact right of inheritance)!
