Fear Allah in your affairs even if the whole world and those you love turn against you, mock you and ridicule you. Who cares if they think you're being extreme, admonish them gently and continuously, evenif they turn away from you every time, because if the punishment of Allah comes upon you for trying to please the people instead of Allah, you will find no helper or aid, and you will be among the losers in this world and even greater in the hereafter.
- Umar
Let there arise out of you a group of people inviting to all that is good (Islam), enjoining Al-Ma‘roof (i.e. Islamic Monotheism and all that Islam orders one to do) and forbidding Al-Munkar (polytheism and disbelief and all that Islam has forbidden). And it is they who are the successful. [Aal ‘Imraan 3:104]
