A thought came up (quelle surprise!) in another thread about how much "social values" are emphasized in a faith tradition, and I wondered what well-known quotes from Qu'ran might be comparable to "True religion is to visit the widows and orphans in their ....." and/or "The fruit of the Spirit is love, joy......"
The Qur'an set up a social structure to prevent widows and orphans from being without assistance or alone. the Ummah is an extended family and each person is responsible to assure no one does without. Polygamy in Islam has the purpose of providing for the care of Widows and orphans. Polygamy in Islam was designed with limitations that would provide for the care of widows and orphans. Add to this the concept of walli's for those unable to care for themselves.
Here are some quotes from the Qur'an and the Ahadith
"And they feed, for the love of Allah, the poor, the orphan, and the captive..." [Surah al-Insaan, 8]
"One who cares for widows and the poor is like those who fight in the way of Allah or those who spend their days fasting and their nights praying." [Agreed upon, also in Adab al-Mufrad of Imaam Al-Bukhari in chapter "The Virtue of Those Who Care for Orphans"]
A man once came to the Messenger of Allah, sallallaahu`alaihiwasallam, and complained that he feels hardness in his heart. The Messenger of Allah said, what translated means, "Would you like that your heart becomes soft and that you acquire what you need? Be merciful with the orphan, pat his head and feed him from what you eat. This will soften your heart, and enable you to get what you need." [At-Tabaraanee & As-Silsilah as-Saheehah]
"I and the caretaker of the orphan will enter Paradise together like this, raising (by way of illustration) his forefinger and middle finger jointly, leaving no space in between." [Saheeh al-Bukhaari]
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said: Sponsoring an orphan means taking care of his religious and worldly interests, teaching him and guiding him etc with regard to religious matters, and taking care of his food, drink, shelter and other worldly concerns. [Sharh Riyaadh al-Saaliheen, 5/113]
"You shall hand over to the ORPHANS* their rightful properties. Do not substitute the bad for the good, and do not consume their properties by combining them with yours. This would be a gross injustice. If you fear that you will not be equitable towards the ORPHANS*, then you may marry their mothers. You may marry two, three, or four. If you fear lest you become unfair, then you shall be content with only one, or with what you already have. Additionally, you are thus more likely to avoid financial hardship." (4/2-3)
