​Agriculture

Every single Muslim that plants or cultivates anything of which humans, animals or birds may eat from is counted as charity towards them on his behalf.

رسولُ اللَّهِ صلى اللَّه عليه وآله :  ما مِن مسلِمٍ يَغرِسُ غَرساً أو يَزرَعُ زَرعاً ، فَيَأكُلُ مِنهُ طَيرٌ أو إنسانٌ أو بَهيمِةٌ ، إلّا كانَ لَهُ بِه صَدَقةٌ . صحيح البخاري : 2 / 817 / 2195 .

 The Prophet (SAWA) said, 'Every single Muslim that plants or cultivates anything of which humans, animals or birds may eat from is counted as charity towards them on his behalf.'
