Moulana Ali(SA) said Advice for observing courtesy and kindness and keeping in and out of the same

The young among you should follow the elders while the elders should be kind to the young. Do not be like those rude people of the pre-lslamic (al-jáhiliyyah) period who did not exert themselves in religion nor use their intellects in the matter of Alláh. They are like the breaking of eggs in the nest of a dangerous bird, because their breaking looks bad, but keeping them intact would mean the production of dangerous young ones.
