In the Islamic world there are no old people's homes. The strain of caring for one's parents in this most difficult time of their lives is considered an honor and blessing, and an opportunity for great spiritual growth. God asks that we not only pray for our parents, but act with limitless compassion, remembering that when we were helpless children they preferred us to themselves. Mothers are particularly honored: the Prophet taught that 'Paradise lies at the feet of mothers'. When they reach old age, Muslim parents are treated mercifully, with the same kindness and selflessness.
In Islam, serving one's parents is a duty second only to prayer, and it is their right to expect it. It is considered despicable to express any irritation when, through no fault of their own, the old become difficult.
The Quran says: Your Lord has commanded that you worship none but Him, and be kind to parents. If either or both of them reach old age with you, do not say 'uff to them or chide them, but speak to them in terms of honor and kindness. Treat them with humility, and say, 'My Lord! Have mercy on them, for they did care for me when I was little'. (17:23-4)
