Wisdom from Prophets

He who wishes to enter Paradise must please his father and mother -Prophet Muhammad (PBUH)

Wisdom from Quran

Allah has promised, to those among you who believe and work righteous deeds, that He will, of a surety grant them in the land, inheritance (of power), as He granted it to those before them; that He will establish in authority their religion -- the one which He has chosen for them; and that He will change (their state), after the fear in which they (lived), to one of security and peace.

They will worship Me (alone) and not associate aught with Me. If any do reject faith after this, they are rebellious and wicked. So establish regular prayer and give regular charity; and obey the apostle; that ye may receive mercy. Never think thou that the unbelievers are going to frustrate (Allah's plan) on earth: their abode is the Fire, -- and it is indeed an evil refuge! - The Holy Qur'an (24: 55-57)

Wisdom from Imams

Live among people in such a way that they weep for you when you die and wish to have your company during your lifetime. Imam Ali (A.S.)
