Sayyiduna Anas (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) advised me, so he said: "O Anas! Perform ablution completely, your life will be prolonged. Greet everyone you meet from my Ummah, your good deeds will increase. And when you enter your house, greet your family. And perform the Duha prayer, for it is the prayer of the penitent. Show mercy to the young and honor the elders, and you will be among my companions on the Day of Resurrection."
