O you who believe! answer (the call of) Allah and His Messenger when he calls you to that which gives you life; and know that Allah intervenes between man and his heart, and that to Him you shall be gathered.

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;

(This is Our) course with regard to those of Our messengers whom We sent before you, and you shall not find a change in Our course.
