Hadith
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، حَدَّثَنَا ابْنُ جُرَيْجٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ أَطْعَمَهُ اللَّهُ طَعَامًا فَلْيَقُلِ اللَّهُمَّ بَارِكْ لَنَا فِيهِ وَارْزُقْنَا خَيْرًا مِنْهُ . وَمَنْ سَقَاهُ اللَّهُ لَبَنًا فَلْيَقُلِ اللَّهُمَّ بَارِكْ لَنَا فِيهِ وَزِدْنَا مِنْهُ فَإِنِّي لاَ أَعْلَمُ مَا يُجْزِئُ مِنَ الطَّعَامِ وَالشَّرَابِ إِلاَّ اللَّبَنُ " .
It was narrated from Ibn ‘Abbas that the Messenger of Allah (ﷺ) said:“Whoever is given food by Allah, let him say: Allahumma barik lana fihi wa arzuqna khairan minhu (O Allah, bless it for us and provide us with something better than it). And whoever is given milk to drink by Allah, let him say: Allahumma barik lana fihi wa zidna minhu (O Allah, bless it for us and give us more of it). For I do not know of any food or drink that suffices, apart from milk.”
