1249. hadíth
وَ سَأَلَهُ سَمَاعَةُ: عَنِ اَللَّبَنِ يُشْتَرَى وَ هُوَ فِي اَلضُّرُوعِ فَقَالَ "لاَ إِلاَّ أَنْ يَحْلُبَ لَكَ مِنْهُ سُكُرُّجَةً فَتَقُولُ أَشْتَرِي مِنْكَ هَذَا اَللَّبَنَ اَلَّذِي فِي اَلسُّكُرُّجَةِ وَ مَا فِي ضُرُوعِهَا بِثَمَنٍ مُسَمًّى فَإِنْ لَمْ يَكُنْ فِي اَلضُّرُوعِ شَيْءٌ كَانَ فِيمَا فِي اَلسُّكُرُّجَةِ".
Samaah asked him about purchasing milk while it is still in the udders. Imam (a.s) said: "No, unless he milks some of it into a small vessel (sukurjah) for you, and then you say, 'I purchase from you this milk that is in the vessel and what is in its udders for a specified price.' If there is nothing in the udders, then the sale applies to what is in the vessel."
