(5) باب الْغَدْوَةِ وَالرَّوْحَةِ فِي سَبِيلِ اللَّهِ، وَقَابُ قَوْسِ أَحَدِكُمْ مِنَ الْجَنَّةِ
Narrated Abu Huraira:
The Prophet (ﷺ) said, "A place in Paradise as small as a bow is better than all that on which the sun rises and sets (i.e. all the world)." He also said, "A single endeavor in Allah's Cause in the afternoon or in the forenoon is better than all that on which the sun rises and sets."
