عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ الْأَشْعَرِيِّ عَنِ ابْنِ الْقَدَّاحِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ كَانَ النَّبِيُّ ( صلى الله عليه وآله ) إِذَا شَرِبَ اللَّبَنَ قَالَ اللَّهُمَّ بَارِكْ لَنَا فِيهِ وَ زِدْنَا مِنْهُ .

3. A number of our people have narrated from Sahl ibn Ziyad from Ja’far ibn Muhammad al-Ash‘ariy from ibn al-Qaddah who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, when drinking milk would say, ‘O Lord, make it a blessing for us and increase it for us.’”
