عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ أَلَا لَا تُحْتَلَبَنَّ مَاشِيَةُ امْرِئٍ إِلَّا بِإِذْنِهِ أَيُحِبُّ أَحَدُكُمْ أَنْ تُوتَى مَشْرَبَتُهُ فَيُكْسَرَ بَابُهَا ثُمَّ يُنْتَثَلَ مَا فِيهَا فَإِنَّ مَا فِي ضُرُوعِ مَوَاشِيهِمْ طَعَامُ أَحَدِهِمْ أَلَا فَلَا تُحْلَبَنَّ مَاشِيَةُ امْرِئٍ إِلَّا بِإِذْنِهِ أَوْ قَالَ بِأَمْرِهِ
Narrated by Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Beware! Do not milk someone’s cattle without their permission. Do you like that someone comes into your upper chamber, breaks its door, and takes away what is inside? In the same way, what is in the udders of the cattle belongs to their owners as food. Beware! Do not milk someone’s cattle without their permission or command.
