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 wasnarrated from Ibn ‘Abbas that the Messenger of Allah (PBUH)said: “Whoever is given food by Allah, let him say: Allahumma bariklanafihi wa arzuqna khairan minhu (O Allah, bless it for us andprovideus with something better than it). And whoever is given milkto drinkby Allah, let him say: Allahumma barik lana fihi wa zidnaminhu (OAllah, bless it for us and give us more of it). For I do notknow ofany food or drink that suffices, apart from milk.” Translation Not Available
