Old parents, kids, orphans, needy, widows, and divorced women are the most vulnerable people in our society. Let's take a look what the Qur'an says about them. Parents care: 17.23: Thy Lord hath decreed that ye worship none but Him, and that ye be kind to parents. Whether one or both of them attain old age in thy life, say not to them a word of contempt, nor repel them, but address them in terms of honour. 46.15: We have enjoined on man kindness to his parents: In pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says, "O my Lord! Grant me that I may be grateful for Thy favour which Thou has bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam." 4.36: Serve Allah, and join not any partners with Him; and do good- to parents, kinsfolk, orphans, those in need, neighbours who are near, neighbours who are strangers, the companion by your side, the wayfarer (ye meet), and what your right hands possess: For Allah loveth not the arrogant, the vainglorious. 2.83: And remember We took a covenant from the Children of Israel (to this effect): Worship none but Allah; treat with kindness your parents and kindred, and orphans and those in need; speak fair to the people; be steadfast in prayer; and practise regular charity. Then did ye turn back, except a few among you, and ye backslide (even now). Child care: 6.151: Say: "Come, I will rehearse what Allah hath (really) prohibited you from": Join not anything as equal with Him; be good to your parents; kill not your children on a plea of want;- We provide sustenance for you and for them;- come not nigh to shameful deeds. Whether open or secret; take not life, which Allah hath made sacred, except by way of justice and law: thus doth He command you, that ye may learn wisdom. 2.233: The mothers shall give such to their offspring for two whole years, if the father desires to complete the term. But he shall bear the cost of their food and clothing on equitable terms. No soul shall have a burden laid on it greater than it can bear. No mother shall be treated unfairly on account of her child. Nor father on account of his child, an heir shall be chargeable in the same way. If they both decide on weaning, by mutual consent, and after due consultation, there is no blame on them. If ye decide on a foster-mother for your offspring, there is no blame on you, provided ye pay (the mother) what ye offered, on equitable terms. But fear Allah and know that Allah sees well what ye do. Orphans and needy care: 2.177: It is not righteousness that ye turn your faces Towards East or West; but it is righteousness- to believe in Allah and the Last Day, and the Angels, and the Book, and the Messengers; to spend of your substance, out of love for Him, for your kin, for orphans, for the needy. 2.215: They ask thee what they should spend (In charity). Say: Whatever ye spend that is good, is for parents and kindred and orphans and those in want and for wayfarers. And whatever ye do that is good, -Allah knoweth it well. 2.220: (Their bearings) on this life and the Hereafter. They ask thee concerning orphans. Say: "The best thing to do is what is for their good; if ye mix their affairs with yours, they are your brethren; but Allah knows the man who means mischief from the man who means good. And if Allah had wished, He could have put you into difficulties: He is indeed Exalted in Power, Wise." 4.2: To orphans restore their property (When they reach their age), nor substitute (your) worthless things for (their) good ones; and devour not their substance (by mixing it up) with your won. For this is indeed a great sin. 4.8: But if at the time of division other relatives, or orphans or poor, are present, feed them out of the (property), and speak to them words of kindness and justice. 4.10: Those who unjustly eat up the property of orphans, eat up a Fire into their own bodies: They will soon be enduring a Blazing Fire! 4.36: Serve Allah, and join not any partners with Him; and do good- to parents, kinsfolk, orphans, those in need, neighbours who are near, neighbours who are strangers, the companion by your side, the wayfarer (ye meet), and what your right hands possess: For Allah loveth not the arrogant, the vainglorious. 9.60: Alms are for the poor and the needy, and those employed to administer the (funds); for those whose hearts have been (recently) reconciled (to Truth); for those in bondage and in debt; in the cause of Allah; and for the wayfarer: (thus is it) ordained by Allah, and Allah is full of knowledge and wisdom. 17.26: And render to the kindred their due rights, as (also) to those in want, and to the wayfarer: But squander not (your wealth) in the manner of a spendthrift. 93.9-10: Therefore, treat not the orphan with harshness. Therefor the beggar drive not away. 107.1-3: Do you know who really rejects the faith? That is the one who mistreats the orphans. And does not advocate the feeding of the poor. 2.43: And keep up prayer and pay the poor-rate and bow down with those who bow down. Widows and divorced women care: 2.240-241: 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. For divorced women Maintenance (should be provided) on a reasonable (scale). This is a duty on the righteous. Widows and divorced women can re-marry, if they wish (2:234-240, 2:229, 2:232).
