Narrated Abu Huraira (Radi-Allahu 'anhu):

I heard Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) saying, "Anybody who
spends a pair of something in Allah's Cause will be called from all the
gates of Paradise, 'O Allah's slave! This is good.'

He who is amongst those who pray will be called from the gate of the prayer
(in Paradise) and he who is from the people of Jihad will be called from
the gate of Jihad, and he who is from those who give in charity (i.e.
Zakat) will be called from the gate of charity, and he who is amongst those
who observe fast will be called from the gate of fasting, the gate of
Raiyan."

Abu Bakr said, "He who is called from all those gates will need nothing,"
He added, "Will anyone be called from all those gates, O Allah's Apostle?"
He said, "Yes, and I hope you will be among those, O Abu Bakr."
