In the Islamic world, there are no old people's homes. The duty of caring for one's parents in this most difficult time of their lives is considered as an honour, a blessing, an opportunity to earn a great reward, and a way to increase one's spiritual growth. Allah asks that we not only pray for our parents, but that we act with limitless compassion towards them and remember that when we were helpless children, they preferred us to themselves.
Mothers are particularly honoured. The prophet taught that: “Paradise lies at the feet of mothers” and when they reach old age, parents are treated mercifully, with kindness and selflessness.
This code of conduct towards one’s parents, whether they be Muslim or non-Muslim, can be summed up in the following verse of the Qur’an:
“Your Lord has commanded that you worship none but Him and that you be kind to your parents. If either or both of them reach old age with you, do not (even) say ‘ugh’ (do not even so much as make a face or sigh) to them or rebuke them, but speak to them in terms of honour and kindness. Treat them with humility and say: My Lord! Have mercy on them, for they did care for me when I was little.” (al-Qur’an, Chapter 17, Verse 23-24)
