عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ أَطْعَمَهُ اللَّهُ طَعَامًا فَلْيَقُلْ اللَّهُمَّ بَارِكْ لَنَا فِيهِ وَأَطْعِمْنَا خَيْرًا مِنْهُ وَمَنْ سَقَاهُ اللَّهُ لَبَنًا فَلْيَقُلْ اللَّهُمَّ بَارِكْ لَنَا فِيهِ وَزِدْنَا مِنْهُ فَإِنَّهُ لَيْسَ شَيْءٌ يُجْزِئُ مَكَانَ الطَّعَامِ وَالشَّرَابِ غَيْرُ اللَّبَنِ
Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: Whoever is provided food by Allah, let him say: "O Allah! Bless it for us and provide us with better than it." And whoever is provided milk to drink by Allah, let him recite this supplication: "O Allah! Bless it for us and increase it for us." Milk alone suffices in place of both food and drink.
