«آمركم بثلاث وأنهاكم عن ثلاث آمركم أن تعبدوا الله ولا تشركوا به شيئا وأن تعتصموا بحبل الله جميعا ولا تفرقوا وتسمعوا وتطيعوا لمن ولاه الله أمركم وأنهاكم عن قيل وقال وكثرة السؤال وإضاعة المال»
The Prophet (peace and blessings be upon him) said:
"I command you to do three things and forbid you from three things. I command you to worship Allah and not associate anything with Him, to hold fast all together to the rope of Allah and not be divided, and to listen to and obey the one whom Allah has put in charge of your affairs (that is, the ruler). And I forbid you from 'it was said and he said' (idle argument or spreading rumours), from asking much (begging without need or asking needless questions), and from wasting wealth."
