عَنِ الْمِقْدَامِ بْنِ مَعْدِي كَرِبَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَا أَطْعَمْتَ نَفْسَكَ فَهُوَ لَكَ صَدَقَةٌ، وَمَا أَطْعَمْتَ وَلَدَكَ فَهُوَ لَكَ صَدَقَةٌ، وَمَا أَطْعَمْتَ زَوْجَكَ فَهُوَ لَكَ صَدَقَةٌ، وَمَا أَطْعَمْتَ خَادِمَكَ فَهُوَ لَكَ صَدَقَةٌ))
It is narrated from Sayyiduna Miqdam bin Ma’di Karib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whatever you feed yourself, it will be charity for you; whatever you feed your children, that too will be charity on your behalf; whatever you feed your wife, that too will be your charity; and whatever you feed your servant, that too will be charity on your behalf.
