The Prophet ﷺ said: When one of you comes to the cattle, he should seek permission of their master if he is there; if he permits, he should milk (the animals) and drink. If he is not there, he should call three times. If he responds, he should seek his permission; otherwise, he may milk (the animals) and drink, but should not carry (with him).  

أَنَّ نَبِيَّ اللَّهِ ﷺ قَالَ إِذَا أَتَى أَحَدُكُمْ عَلَى مَاشِيَةٍ فَإِنْ كَانَ فِيهَا صَاحِبُهَا فَلْيَسْتَأْذِنْهُ فَإِنْ أَذِنَ لَهُ فَلْيَحْلِبْ وَلْيَشْرَبْ فَإِنْ لَمْ يَكُنْ فِيهَا فَلْيُصَوِّتْ ثَلاَثًا فَإِنْ أَجَابَهُ فَلْيَسْتَأْذِنْهُ وَإِلاَّ فَلْيَحْتَلِبْ وَلْيَشْرَبْ وَلاَ يَحْمِلْ  

I suffered from drought; so I entered a garden of Medina, and rubbed an ear-corn. I ate and carried in my garment. Then its master came, he beat me and took my garment. He came to the Messenger of Allah ﷺ who said to him: You did not teach him if he was ignorant; and you did not feed him if he was hungry. He ordered him, so he returned my garment to me, and gave me one or half a wasq (sixty or thirty sa's) of corn.  

أَصَابَتْنِي سَنَةٌ فَدَخَلْتُ حَائِطًا مِنْ حِيطَانِ الْمَدِينَةِ فَفَرَكْتُ سُنْبُلاً فَأَكَلْتُ وَحَمَلْتُ فِي ثَوْبِي فَجَاءَ صَاحِبُهُ فَضَرَبَنِي وَأَخَذَ ثَوْبِي فَأَتَيْتُ رَسُولَ اللَّهِ ﷺ فَقَالَ لَهُ مَا عَلَّمْتَ إِذْ كَانَ جَاهِلاً وَلاَ أَطْعَمْتَ إِذْ كَانَ جَائِعًا أَوْ قَالَ سَاغِبًا وَأَمَرَهُ فَرَدَّ عَلَىَّ ثَوْبِي وَأَعْطَانِي وَسْقًا أَوْ نِصْفَ وَسْقٍ مِنْ طَعَامٍ  

Abu Bishr said “I heard ‘Abbad bin ‘Shurahbil a man of us from Banu Ghubar. He narrated the reast of the tradition to the same effect.”  

سَمِعْتُ عَبَّادَ بْنَ شُرَحْبِيلَ رَجُلاً مِنَّا مِنْ بَنِي غُبَرَ بِمَعْنَاهُ
