The Book of Miscellany
Sustentation of the Members of the Family
وَعَنْ أَبِي مسعود الْبَدْرِيِّ رَضِيَ اللهُ عَنْهُ، عَنِ النَّبِيِّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: إِذَا أَنْفَقَ الرَّجُلُ عَلَى أَهْلِهِ نفقة يحتسبها فهي له صدقة ((مُتَّفَقٌ عَلَيْهِ)).
Abu Mas'ud Al-Badri (May Allah be pleased with him) reported: The Prophet (ﷺ) said, "When someone spends on his family seeking his reward for it from Allah, it is counted as a charity from him". [Al-Bukhari and Muslim].
