“The Messenger of Allah ﷺ would say, when milk was brought to him: ‘A blessing,’ or ‘Two blessings.’”  

سَمِعْتُ عَائِشَةَ تَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا أُتِيَ بِلَبَنٍ قَالَ بَرَكَةٌ أَوْ بَرَكَتَانِ  

“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.”  

قَالَ رَسُولُ اللَّهِ ﷺ 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
