Emigrates for Allah

It was not fitting for the people of Medina and those around them to stay behind when Allah’s Messenger marched forth, nor to prefer their own comfort over his. They did not suffer thirst, fatigue, or hunger in Allah’s cause, nor take a step that enraged the enemy, nor gain anything from them, without it being recorded as a righteous deed. Allah does not let the reward of the righteous go to waste.

9:120It is not for the townsfolk of Al-Madinah and for those around them of the wandering Arabs so stay behind the messenger of Allah and prefer their lives to his life. That is because neither thirst nor toil nor hunger afflicteth them in the way of Allah, nor step they any step that angereth the disbelievers, nor gain they from the enemy a gain, but a good deed is recorded for them therefor. Lo! Allah loseth not the wages of the good.
