allah the almighty said and do not spend wastefully. indeed the wasteful are brothers of the devils. he said and they ask you what they should spend. say the excess. so he gave permission for the excess but did not give permission for the effort. he gave permission for the superfluous but did not give permission for the origins. kab ibn malik 6 wanted to give his money in charity so the prophet may allah bless him and grant him peace said to him keep your money. the prophet may allah bless him and grant him peace forbade him from giving his money in charity and you are ordering him to give it in extravagance.
