Wisdom from Prophets

Much silence and a good disposition; there are no two works better than these --Prophet Muhammad (PBUH)

Wisdom from Quran

The worldly things which ye are given are but the conveniences of this life and the glitter thereof; but that which is with Allah is better and more enduring: will ye not then be wise? (28:60)

Wisdom from Imams

A conceited and self-admiring person is disliked by others; charity and alms are the best remedy for ailments and calamities; one has to account in the next world for the deeds that he has done in this world. Imam Ali (A.S.)
