The more you volunteer, the happier you are. Volunteering builds empathy, strengthens social bonds and makes you smile — all factors that increase the feeling of love.
The Messenger, peace and blessings be upon him, said:
“The most beloved people to Allah are those who are most beneficial to people. The most beloved deed to Allah is to make a Muslim happy, or to remove one of his troubles, or to forgive his debt, or to feed his hunger."
(al-Muʻjam al-Awsaṭ)
