6- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ أَخِيهِ الْحَسَنِ عَنْ زُرْعَةَ عَنْ سَمَاعَةَ قَالَ سَأَلْتُهُ عَنِ اللَّبَنِ يُشْتَرَى وَهُوَ فِي الضَّرْعِ قَالَ لا إِلا أَنْ يَحْلُبَ لَكَ سُكُرُّجَةً فَيَقُولَ اشْتَرِ مِنِّي هَذَا اللَّبَنَ الَّذِي فِي السُّكُرُّجَةِ وَمَا فِي ضُرُوعِهَا بِثَمَنٍ مُسَمًّى فَإِنْ لَمْ يَكُنْ فِي الضُّرُوعِ شَيْءٌ كَانَ مَا فِي السُّكُرُّجَةِ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from his brother al-Hassan from Zurarah from Sanaa ‘ah who has said the following: “I once asked him (the Imam) 
, if milk which still is in the udder can be purchased. He (the Imam) said, ‘No, until it is milked in al-Sukurrujah (a bowl) and the seller can say, “Buy what is in al-Sukurruajah and that which is in the udder for the named price” and if there is nothing in the udder that which is in al-Sukurruajah is what is sold.’”
