'I hereby reiterate what I have said: establish the performance of the prayer, pay the alms-tax, enjoin what is good, and forbid evil. Verily the peak of enjoining what is good and forbidding evil is to heed to my words and propagate them to those who are absent; you must command them to accept [my words] and prohibit them from going against them, for they are the commands from Allah, the Exalted, and from me.'
