O you who believe! obey Allah and obey the Messenger and those in authority from among you; then if you quarrel about anything, refer it to Allah and the Messenger, if you believe in Allah and the last day; this is better and very good in the end.

They swear by Allah that they did not speak, and certainly they did speak, the word of unbelief, and disbelieved after their Islam, and they had determined upon what they have not been able to effect, and they did not find fault except because Allah and His Messenger enriched them out of His grace; therefore if they repent, it will be good for them; and if they turn back, Allah will chastise them with a painful chastisement in this world and the hereafter, and they shall not have in the land any guardian or a helper.

And We have not sent before you but men from (among) the people of the towns, to whom We sent revelations. Have they not then travelled in the land and seen what was the end of those before them? And certainly the abode of the hereafter is best for those who guard (against evil); do you not then understand?
