It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'Whoever spends on a pair (of things) in the cause of Allah, the gatekeepers of Paradise will call him from the gates of Paradise (saying): O So-and-so, come and enter!' Abu Bakr said: 'O Messenger of Allah, such a person will never perish or be miserable.' The Messenger of Allah (ﷺ) said: 'I hope that you will be one of them.'"
