Live in big cities because they are collective centres of the Muslims. Avoid places of neglectfulness and wickedness and places where there are paucity of supporters for the obedience of Allāh. Confine your thinking to matters which are helpful to you. Do not sit in the marketing centres because they are the meeting-places of Satan, and targets of mischiefs. Frequently look at those over whom you enjoy superiority because this is a way of giving thanks.
