The real work of a prophet is warning the people, i.e. informing them of the serious nature of the events which will unfold in the Hereafter. This task can be performed only by one whose heart is overflowing with the realisation of God’s Majesty, who possesses a noble character, who shuns all evil, who does good without aspiring to any recompense, who can be unilaterally tolerant and exercise patience in the face of trouble created by others.
