254. O you who have faith in Allah and follow His Messenger, spend from the different types of permissible wealth that Allah has provided for you before the Day of Resurrection comes. On that day, there will be no sale so that a person may buy something of use to him, nor friendship that will be of benefit at a time of difficulty, and no intermediary that will protect him from any harm or bring any benefit unless Allah allows. The disbelievers are in the wrong due to their denial of Allah.
