عَنْ ضَرَارِ بْنِ الْأَزْوَرِ رَضِيَ اللَّهُ عَنْهُ قَالَ أَهْدَيْنَا لِرَسُولِ اللَّهِ لِقْحَةً (وَفِي رَوَايَةٍ بَعَثَنِي أَهْلِي بِلُقُوحٍ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَأَمَرَنِي أَنْ أَحْلُبَهَا) قَالَ فَحَلَبْتُهَا قَالَ فَلَمَّا أَخَذْتُ لِأُجْهِدَهَا قَالَ لَا تَفْعَلْ دَعْ دَاعِيَ اللَّبَنِ
Sayyiduna Dhirar bin Azwar (may Allah be pleased with him) says: We presented a milch she-camel to the Messenger of Allah (peace and blessings be upon him) as a gift. In another narration, it is stated: Some members of my family sent me with milch she-camels to the Noble Prophet (peace and blessings be upon him). He (peace and blessings be upon him) instructed me to milk them, so I milked them. When I tried, with effort, to extract all the milk, the Prophet (peace and blessings be upon him) said: Do not do it like this; rather, leave the milk that causes (more) milk to be produced (in the udders).
