The word(s) "rightful" appears 21 time(s) in 21 verse(s) in Quran in Muhammad Pickthal translation.

(1) But they who disbelieve, and deny Our revelations, such are rightful Peoples of the Fire. They will abide therein.

(2) Nay, but whosoever hath done evil and his sin surroundeth him; such are rightful owners of the Fire; they will abide therein.

(3) And those who believe and do good works: such are rightful owners of the Garden. They will abide therein.

(4) They question thee (O Muhammad) with regard to warfare in the sacred month. Say: Warfare therein is a great (transgression), but to turn (men) from the way of Allah, and to disbelieve in Him and in the Inviolable Place of Worship, and to expel His people thence, is a greater with Allah; for persecution is worse than killing. And they will not cease from fighting against you till they have made you renegades from your religion, if they can. And whoso becometh a renegade and dieth in his disbelief: such are they whose works have fallen both in the world and the Hereafter. Such are rightful owners of the Fire: they will abide therein.

(5) Allah is the Protecting Guardian of those who believe. He bringeth them out of darkness into light. As for those who disbelieve, their patrons are false deities. They bring them out of light into darkness. Such are rightful owners of the Fire. They will abide therein.

(6) Those who swallow usury cannot rise up save as he ariseth whom the devil hath prostrated by (his) touch. That is because they say: Trade is just like usury; whereas Allah permitteth trading and forbiddeth usury. He unto whom an admonition from his Lord cometh, and (he) refraineth (in obedience thereto), he shall keep (the profits of) that which is past, and his affair (henceforth) is with Allah. As for him who returneth (to usury) - Such are rightful owners of the Fire. They will abide therein.

(7) Lo! the riches and the progeny of those who disbelieve will not avail them aught against Allah; and such are rightful owners of the Fire. They will abide therein.

(8) And they who disbelieve and deny Our revelations, such are rightful owners of hell.

(9) But they who deny Our revelations and scorn them - each are rightful owners of the Fire; they will abide therein.

(10) But (as for) those who believe and do good works - We tax not any soul beyond its scope - Such are rightful owners of the Garden. They abide therein.
