(9:39) If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent. (9:40) If you do not aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise. (9:41) Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only knew. (9:42) Had it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars. (9:43) May Allah pardon you, [O Muhammad]; why did you give them permission [to remain behind]? [You should not have] until it was evident to you who were truthful and you knew [who were] the liars. (9:44) Those who believe in Allah and the Last Day would not ask permission of you to be excused from striving with their wealth and their lives. And Allah is Knowing of those who fear Him. (9:45) Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.
