'Narrated Abu Huraira: Allah's Apostle said, "Whoever gives
two kinds (of things or property) in charity for Allah's
Cause, will be called from the gates of Paradise and will be
addressed, 'O slaves of Allah! Here is prosperity.' So,
whoever was amongst the people who used to offer their
prayers, will be called from the gate of the prayer; and
whoever was amongst the people who used to participate in
Jihad, will be called from the gate of Jihad; and whoever was
amongst those who used to observe fasts, will be called from
the gate of Ar−Raiyan; whoever was amongst those who used to
give in charity, will be called from the gate of charity." Abu
Bakr said, "Let my parents be sacrificed for you, O Allah's
Apostle! No distress or need will befall him who will be
called from those gates. Will there be any one who will be
called from all these gates?" The Prophet replied, "Yes, and I
hope you will be one of them."
