Abu Dharr Al GhifariDo not please the rulers in a way that incurs the wrath of Allah. And if they come up with innovations of which you know not, stay aloof from them; and remain strong against them, even if you were tortured, deprived or rusticated, so that Allah may be pleased with you! Surely, Allah is Most High and it does not behoove to displease Him, by pleasing His creatures. (Abu Dharr al-Ghifari - may Allah bless him with mercy - attributed in Al-Amail, ch. 20, #4).
