What was his advice to the people of Suffa?

Also remember the way he reacted to these rough times, for example:

Dua’a at-Ta’if

“O Allah! Unto You do I complain of my weakness, of my helplessness and of my lowliness before men.  O most Merciful of the merciful. O Lord of the weak and my Lord too. Into whose hands have you entrusted me?  Unto some far off stranger who receives me with hostility? Or unto a foe whom you have empowered against me? I care not, so long as You are not angry with me.  But Your favouring help, that were for me the broader way and the wider scope.  I take refuge in the light of Your countenance whereby all darknesses are illuminated and all things of this world and the next are rightly ordered, lest You make descend Your anger upon me or lest Your wrath beset me. Yet it is Yours to reproach until You are well pleased. There is no power and no might except through Thee.”
