Hadith on Charity: No Muslim plants a tree except that it is rewarded as charity

Anas bin Malik رضي الله عنه narrated: The Messenger of Allah صلى الله عليه وسلم  said, “There is no Muslim who plants a tree or sows seeds and then a bird, or a person, or an animal eats from it except that it is regarded as a charity for him.”
[Sahih Bukhari, Volume 3, Book 39, Number 513]

عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم‏ مَا مِنْ مُسْلِمٍ يَغْرِسُ غَرْسًا، أَوْ يَزْرَعُ زَرْعًا، فَيَأْكُلُ مِنْهُ طَيْرٌ أَوْ إِنْسَانٌ أَوْ بَهِيمَةٌ، إِلاَّ كَانَ لَهُ بِهِ صَدَقَةٌ
