Imam Jafar al-Sadiq (as):
" When you say the name of the Prophet, send lots of Salawat on him. Indeed, whoever sends one Salawat on the Prophet, Allah will send a thousand Salawats on him in the form of a thousand queues of angels and nothing from God’s creation remains unless it will send Salawat on that servant."

Holy Quran: 87:14-17
" Felicitous is he who purifies himself, (14) celebrates the Name of his Lord, and prays. (15) But you prefer the life of this world, (16) while the Hereafter is better and more lasting.(17)"

Prophet Muhammad (p.b.u.h):
“God is not merciful to him who is not so to humankind. He who is not kind to God's creation and to his own children, God will not be kind to him.”

Imam Hasan Askari (as):
“The most pious of people is he who refrains before suspicion. The most worshipful of people is he who keeps on obligations. The most ascetic one is he who refrains from unlawful things. The best mujtahid is he who refrains from sins.”
