Messenger of Allah (salAllahu alayhi wa sallam) said:
"Do not disdain a good deed, (no matter how small it may seem) even if it is your meeting with your (Muslim) brother with a cheerful face.''
[Muslim]
Commentary:
Every deed approved by the Shari`ah is considered good and rewarding. Howsoever seemingly small people may consider it, it must not be looked at from a highbrow angle. Even to meet people cheerfully is one of the Islamic virtues, though it may appear quite insignificant to some people.
