Imam Abu Dawud : 1427

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا جَرِيرٌ عَنْ الْأَعْمَشِ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ قَالَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ خَيْرَ الصَّدَقَةِ مَا تَرَكَ غِنًى أَوْ تُصُدِّقَ بِهِ عَنْ ظَهْرِ غِنًى وَابْدَأْ بِمَنْ تَعُولُ

Narrated to us ['Utsman bin Abu Syaibah], narrated to us [Jarir] from [Al A'masy] from [Abu Shalih] from [Abu Hurairah], he said: The Messenger of Allah, peace and blessings be upon him, said: 'Indeed, the best charity is the charity that leaves sufficiency (for the giver), or that is given in a state of sufficiency. And start with those you are responsible for.'
