The Messenger of Allah said: "Whoever provides the food for a fasting person to break his fast with, then for him is the same reward as his (the fasting person's), without anything being diminished from the reward of the fasting person."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ فَطَّرَ صَائِمًا كَانَ لَهُ مِثْلُ أَجْرِهِ غَيْرَ أَنَّهُ لاَ يَنْقُصُ مِنْ أَجْرِ الصَّائِمِ شَيْئًا  

"I heard a freed slave of ours called Laila narrated from [his (Habib's) grandmother] Umm Amarah bint Ka'b Al-Ansar, that the Prophet entered upon her and some food was brought to him. He said: 'Eat.' She said: 'I am fasting.' So the Messenger of Allah said: 'Indeed the angels send Salat upon the fasting person when (others) eat in his presence, until they finish.' And perhaps he said: 'Until they have eaten their fill.'"  

أَنَّ النَّبِيَّ ﷺ دَخَلَ عَلَيْهَا فَقَدَّمَتْ إِلَيْهِ طَعَامًا فَقَالَ كُلِي فَقَالَتْ إِنِّي صَائِمَةٌ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الصَّائِمَ تُصَلِّي عَلَيْهِ الْمَلاَئِكَةُ إِذَا أُكِلَ عِنْدَهُ حَتَّى يَفْرُغُوا وَرُبَّمَا قَالَ حَتَّى يَشْبَعُوا  

The Prophet ﷺ came to visit Sa'd ibn Ubaydah, and he brought bread and olive oil, and he ate (them). Them). Then the Prophet ﷺ said: May the fasting (men) break their fast with you, and the pious eat your food, and the angels pray for blessing on you.  

أَنَّ النَّبِيَّ ﷺ جَاءَ إِلَى سَعْدِ بْنِ عُبَادَةَ فَجَاءَ بِخُبْزٍ وَزَيْتٍ فَأَكَلَ ثُمَّ قَالَ النَّبِيُّ ﷺ أَفْطَرَ عِنْدَكُمُ الصَّائِمُونَ وَأَكَلَ طَعَامَكُمُ الأَبْرَارُ وَصَلَّتْ عَلَيْكُمُ الْمَلاَئِكَةُ
