(9:87) They were satisfied to be with those who stay behind, and their hearts were sealed over, so they do not understand. (9:88) But the Messenger and those who believed with him fought with their wealth and their lives. Those will have [all that is] good, and it is those who are the successful. (9:89) Allah has prepared for them gardens beneath which rivers flow, wherein they will abide eternally. That is the great attainment. (9:90) And those with excuses among the bedouins came to be permitted [to remain], and they who had lied to Allah and His Messenger sat [at home]. There will strike those who disbelieved among them a painful punishment. (9:91) There is not upon the weak or upon the ill or upon those who do not find anything to spend any discomfort when they are sincere to Allah and His Messenger. There is not upon the doers of good any cause [for blame]. And Allah is Forgiving and Merciful. (9:92) Nor [is there blame] upon those who, when they came to you that you might give them mounts, you said, "I can find nothing for you to ride upon." They turned back while their eyes overflowed with tears out of grief that they could not find something to spend [for the cause of Allah]. (9:93) The cause [for blame] is only upon those who ask permission of you while they are rich. They are satisfied to be with those who stay behind, and Allah has sealed over their hearts, so they do not know.
