It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Messenger of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good;

Have you not seen those who are forbidden secret counsels, then they return to what they are forbidden, and they hold secret counsels for sin and revolt and disobedience to the Messenger, and when they come to you they greet you with a greeting with which Allah does not greet you, and they say in themselves: Why does not Allah punish us for what we say? Hell is enough for them; they shall enter it, and evil is the resort.
