The Holy Prophet [s] said: "O' people! Verily, there is no prophet after me, nor any Ummah after you (Muslims). So, take care to worship your Lord, perform your five ritual prayers, fast in the appointed month (Ramadan), make pilgrimage to the House of your Lord (Mecca), give the alms of your wealth in order to purify your souls thereby, and obey the Holders of Authority, so that you enter the Paradise of your Lord."
Khisal-I-Saduq, p. 152
Imam Amir-ul-Mu'mineen Ali [a] said: "Having the Greatness of the Creator in your mind would make you realize the insignificance of the creatures in your view."
