Ibn Abbas (radi Allahu anhu) narrated that the Prophet (sal Allahu alaihi wa sallam) said: “The pious offspring who casts a single look of affection at his parents receives a reward from Allah equal to the reward of an accepted Hajj.” The people enquired: “O Prophet of Allah (sal Allahu alaihi wa sallam), if someone casts a hundred such glances of love and affection at his parents, what then?” The Prophet (sal Allahu alaihi wa sallam) said: “Yes, indeed, even if one does so a hundred times a day, he will get a hundred fold reward. Allah is far greater than you imagine and is completely free from petty narrow mindedness.” [Sahih Muslim]
Kiss a parent today! It doesn't have to be your own, if you are unable to. Kiss your aunt, your grandmother. Show affection for someone your parents loved.
