The Paradise lies in being dutiful to the parents

"O Messenger of Allah! I want to go out and fight (in Jihad) and I have come to ask your advice." He said: "Do you have a mother?" He said: "Yes." He said: "Then stay with her, for Paradise is beneath her feet."

{ And lower to them the wing of humility out of mercy and say, "My Lord, have mercy upon them as they brought me up [when I was] small." }
