The word(s) "poor-due" appears 23 time(s) in 23 verse(s) in Quran in Muhammad Pickthal translation.

(1) Establish worship, pay the poor-due, and bow your heads with those who bow (in worship).

(2) And (remember) when We made a covenant with the Children of Israel, (saying): Worship none save Allah (only), and be good to parents and to kindred and to orphans and the needy, and speak kindly to mankind; and establish worship and pay the poor-due. Then, after that, ye slid back, save a few of you, being averse.

(3) Establish worship, and pay the poor-due; and whatever of good ye send before (you) for your souls, ye will find it with Allah. Lo! Allah is Seer of what ye do.

(4) It is not righteousness that ye turn your faces to the East and the West; but righteous is he who believeth in Allah and the Last Day and the angels and the Scripture and the prophets; and giveth wealth, for love of Him, to kinsfolk and to orphans and the needy and the wayfarer and to those who ask, and to set slaves free; and observeth proper worship and payeth the poor-due. And those who keep their treaty when they make one, and the patient in tribulation and adversity and time of stress. Such are they who are sincere. Such are the Allah-fearing.

(5) Lo! those who believe and do good works and establish worship and pay the poor-due, their reward is with their Lord and there shall no fear come upon them neither shall they grieve.

(6) But those of them who are firm in knowledge and the believers believe in that which is revealed unto thee, and that which was revealed before thee, especially the diligent in prayer and those who pay the poor-due, the believers in Allah and the Last Day. Upon these We shall bestow immense reward.

(7) Allah made a covenant of old with the Children of Israel and We raised among them twelve chieftains, and Allah said: Lo! I am with you. If ye establish worship and pay the poor-due, and believe in My messengers and support them, and lend unto Allah a kindly loan, surely I shall remit your sins, and surely I shall bring you into Gardens underneath which rivers flow. Whoso among you disbelieveth after this will go astray from a plain road.

(8) And ordain for us in this world that which is good, and in the Hereafter (that which is good), Lo! We have turned unto Thee. He said: I smite with My punishment whom I will, and My mercy embraceth all things, therefore I shall ordain it for those who ward off (evil) and pay the poor-due, and those who believe Our revelations;

(9) Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.

(10) But if they repent and establish worship and pay the poor-due, then are they your brethren in religion. We detail Our revelations for a people who have knowledge.
