Encouragement to give in charity even if it is a little, and a little should not be withheld because one thinks it is too little

Sahih Muslim · Book 12 · Hadith 1030

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا اللَّيْثُ بْنُ سَعْدٍ، ح وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا اللَّيْثُ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَقُولُ ‏"‏ يَا نِسَاءَ الْمُسْلِمَاتِ لاَ تَحْقِرَنَّ جَارَةٌ لِجَارَتِهَا وَلَوْ فِرْسِنَ شَاةٍ ‏"‏ ‏.‏

Abu Huraira reported Allah's Messenger (ﷺ) as saying: O Muslim women, none of you should consider even a sheep's trotter too insignificant to give to her neighbour.
