The word(s) "reasonable" appears 11 time(s) in 11 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) O ye who believe! the law of equality is prescribed to you in cases of murder: the free for the free, the slave for the slave, the woman for the woman. But if any remission is made by the brother of the slain, then grant any reasonable demand, and compensate him with handsome gratitude, this is a concession and a Mercy from your Lord. After this whoever exceeds the limits shall be in grave penalty.

(2) It is prescribed, when death approaches any of you, if he leave any goods that he make a bequest to parents and next of kin, according to reasonable usage; this is due from the Allah-fearing.

(3) If any of you die and leave widows behind, they shall wait concerning themselves four months and ten days: When they have fulfilled their term, there is no blame on you if they dispose of themselves in a just and reasonable manner. And Allah is well acquainted with what ye do.

(4) There is no blame on you if ye divorce women before consummation or the fixation of their dower; but bestow on them (A suitable gift), the wealthy according to his means, and the poor according to his means;- A gift of a reasonable amount is due from those who wish to do the right thing.

(5) Those of you who die and leave widows should bequeath for their widows a year's maintenance and residence; but if they leave (The residence), there is no blame on you for what they do with themselves, provided it is reasonable. And Allah is Exalted in Power, Wise.

(6) For divorced women Maintenance (should be provided) on a reasonable (scale). This is a duty on the righteous.

(7) Make trial of orphans until they reach the age of marriage; if then ye find sound judgment in them, release their property to them; but consume it not wastefully, nor in haste against their growing up. If the guardian is well-off, Let him claim no remuneration, but if he is poor, let him have for himself what is just and reasonable. When ye release their property to them, take witnesses in their presence: But all-sufficient is Allah in taking account.

(8) If any of you have not the means wherewith to wed free believing women, they may wed believing girls from among those whom your right hands possess: And Allah hath full knowledge about your faith. Ye are one from another: Wed them with the leave of their owners, and give them their dowers, according to what is reasonable: They should be chaste, not lustful, nor taking paramours: when they are taken in wedlock, if they fall into shame, their punishment is half that for free women. This (permission) is for those among you who fear sin; but it is better for you that ye practise self-restraint. And Allah is Oft-forgiving, Most Merciful.

(9) They swear their strongest oaths by Allah that, if only thou wouldst command them, they would leave (their homes). Say: "Swear ye not; Obedience is (more) reasonable; verily, Allah is well acquainted with all that ye do."

(10) "It would not be reasonable in me if I did not serve Him Who created me, and to Whom ye shall (all) be brought back.
