Once the Prophet (ﷺ) after drinking something in the house of one of the Companions, said -
اَللَّهُمَّ أَطْعِمْ مَنْ أَطْعَمَنِيْ وَاسْقِ مَنْ سَقَانِيْ (وَأَسْقِ مَنْ أَسْقَانِي)
اَللّٰهُمَّ اَطْعِمْ مَنْ اَطْعَمَنِيْ وَاسْقِ مَنْ سَقَانِيْ (وَاَسْقِ مَنْ اَسْقَانِيْ)
Allaahumma 'at'im man 'at'amanee wasqi man saqaanee (in another narration: wa asqee man asqaani)
O Allah, feed the one who has fed me and drink to the one who has given me drink.
أَفْطَرَ عِنْدَكُمُ الصَّائِمُوْنَ، وَأَكَلَ طَعَامَكُمُ الْأَبْرَارُ وَصَلَّتْ عَلَيْكُمُ الْمَلَائِكَةُ
اَفْطَرَ عِنْدَكُمُ الصَّائِمُوْنَ، وَاَكَلَ طَعَامَكُمُ الْاَبْرَارُ وَصَلَّتْ عَلَيْكُمُ الْمَلَائِكَةُ
Aftara 'indakumus-saa'imoon, wa 'akala ta'aamakumul-'abraar, wa sallat 'alaykumul-malaa'ikah
With you, those who are fasting have broken their fast, those who are righteous shall fed by you, and the angels recite their prayers upon you.
If someone breaks the fast of Rasulullah (ﷺ) or feeds any food other than fasting, he would say du'a for him by saying this - (The dua is mentioned above)
اَللَّهُمَّ بَارِكْ لَهُمْ فِي مَا رَزَقْتَهُمْ وَاغْفِرْ لَهُمْ وَارْحَمْهُمْ
اَللّٰهُمَّ بَارِكْ لَهُمْ فِيْ مَا رَزَقْتَهُمْ وَاغْفِرْ لَهُمْ وَارْحَمْهُمْ
Allaahumma baarik lahum feemaa razaqtahum, waghfir lahum warhamhum
O Allah, bless them in what You have provided for them, and forgive them and have mercy on them.
Abdullah ibn Bishar said, "The Messenger of Allah (ﷺ) came to my father's house." He offered some food. He took some food from it. My father wants to pray for him. Then he said these words- (The dua is mentioned above)
