Abu Hurairah narrated that Abu Bakr bin Abu Quhafah narrated that the Messenger of Allah ﷺ said to him and to ‘Umar:
“Let us go out to Waqifi.” He said: “So we went out in the moonlight until we came to the garden and he (the owner of the garden) said: ‘Welcome.’ Then he took up the knife and went among the sheep (to choose one for slaughter), and the Messenger of Allah ﷺ said: ‘Avoid those that are lactating.’”

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ الْمُحَارِبِيُّ، عَنْ يَحْيَى بْنِ عُبَيْدِ اللَّهِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ حَدَّثَنِي أَبُو بَكْرِ بْنُ أَبِي قُحَافَةَ، أَنَّ رَسُولَ اللَّهِ ـ ﷺ ـ قَالَ لَهُ وَلِعُمَرَ " انْطَلِقُوا بِنَا إِلَى الْوَاقِفِيِّ " . قَالَ فَانْطَلَقْنَا فِي الْقَمَرِ حَتَّى أَتَيْنَا الْحَائِطَ فَقَالَ مَرْحَبًا وَأَهْلاً . ثُمَّ أَخَذَ الشَّفْرَةَ ثُمَّ جَالَ فِي الْغَنَمِ فَقَالَ رَسُولُ اللَّهِ ـ ﷺ ـ " إِيَّاكَ وَالْحَلُوبَ " . أَوْ قَالَ " ذَاتَ الدَّرِّ " .
