Sunan an-Nasa'i, Volume 3, Book 23, Hadith 2583 (DarusSalam) ⓘ

It was narrated from Salman bin 'Amir that the Prophet said: "Giving charity to a poor person is charity, and (giving) to a relative is two things, charity and upholding the ties of kinship."

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا ابْنُ عَوْنٍ، عَنْ حَفْصَةَ، عَنْ أُمِّ الرَّائِحِ، عَنْ سَلْمَانَ بْنِ عَامِرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ إِنَّ الصَّدَقَةَ عَلَى الْمِسْكِينِ صَدَقَةٌ وَعَلَى ذِي الرَّحِمِ اثْنَتَانِ صَدَقَةٌ وَصِلَةٌ ‏" ‏ ‏.‏
