Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah Narrated Abu Huraira (Radi-Allahu ‘anhu):

I heard the Prophet (Sallallahu ‘Alaihi Wa Sallam) saying, “Who ever spends a couple (of objects) in Allah’s cause, will be called by the Gatekeepers of Paradise who will say, "O so-and-so, come on!” Abu Bakr said, “Such a person will never perish or be miserable.” The Prophet (Sallallahu ‘Alaihi Wa Sallam) said, “I hope you will be among such persons.”
