It was narrated that Muslim bin Thafihan said:

"Ibn 'Alqamah appointed my father to be in charge of his people, and he commanded him to collect their Sadaqah. My father sent me to a group of them to bring their Sadaqah to him. I set out and came to an old man who was called Sa'r. I said: My father has sent me to collect the Sadaqah of your sheep. 'He said: O son of my brother, how will you decode what you want to take?' I said" 'We choose, and we even measure the sheep's udders.' He said: O son of my brother, I tell you that I was in one of these mountain passes at the time of the Messenger of Allah with some sheep of mine. Two men came on a camel and said: We are the messengers of the Messengers of Allah, we come to take the Sadaqah of your sheep. I said: What do I have to give? They said: A sheep. So I went to a sheep that I knew was filled with milk and was fat, and brought it out to them. He said: This is a Shafi - a sheep that has a child or is pregnant - and the Messenger of Allah forbade us to take a Shafi'. So I went to a Mu'tat she-goat - a Mutat is one that has not given birth before, but has reached the age where it could produce young- and brought it out to them. They said: We will take it. So I lifted it up to them, and they took it with them on their camel and left."'

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ، قَالَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا زَكَرِيَّا بْنُ إِسْحَاقَ، عَنْ عَمْرِو بْنِ أَبِي سُفْيَانَ، عَنْ مُسْلِمِ بْنِ ثَفِنَةَ، قَالَ اسْتَعْمَلَ ابْنُ عَلْقَمَةَ أَبِي عَلَى عِرَافَةِ قَوْمِهِ وَأَمَرَهُ أَنْ يُصَدِّقَهُمْ، فَبَعَثَنِي أَبِي إِلَى طَائِفَةٍ مِنْهُمْ لآتِيَهُ بِصَدَقَتِهِمْ فَخَرَجْتُ حَتَّى أَتَيْتُ عَلَى شَيْخٍ كَبِيرٍ يُقَالُ لَهُ سَعْرٌ فَقُلْتُ إِنَّ أَبِي بَعَثَنِي إِلَيْكَ لِتُؤَدِّيَ صَدَقَةَ غَنَمِكَ . قَالَ ابْنَ أَخِي وَأَىُّ نَحْوٍ تَأْخُذُونَ قُلْتُ نَخْتَارُ حَتَّى إِنَّا لَنَشْبُرُ ضُرُوعَ الْغَنَمِ . قَالَ ابْنَ أَخِي فَإِنِّي أُحَدِّثُكَ أَنِّي كُنْتُ فِي شِعْبٍ مِنْ هَذِهِ الشِّعَابِ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فِي غَنَمٍ لِي فَجَاءَنِي رَجُلاَنِ عَلَى بَعِيرٍ فَقَالاَ إِنَّا رَسُولاَ رَسُولِ اللَّهِ ﷺ إِلَيْكَ لِتُؤَدِّيَ صَدَقَةَ غَنَمِكَ . قَالَ قُلْتُ وَمَا عَلَىَّ فِيهَا قَالاَ شَاةٌ . فَأَعْمِدُ إِلَى شَاةٍ قَدْ عَرَفْتُ مَكَانَهَا مُمْتَلِئَةً مَحْضًا وَشَحْمًا فَأَخْرَجْتُهَا إِلَيْهِمَا فَقَالَ هَذِهِ الشَّافِعُ . وَالشَّافِعُ الْحَائِلُ وَقَدْ نَهَانَا رَسُولُ اللَّهِ ﷺ أَنْ نَأْخُذَ شَافِعًا قَالَ فَأَعْمِدُ إِلَى عَنَاقٍ مُعْتَاطٍ - وَالْمُعْتَاطُ الَّتِي لَمْ تَلِدْ وَلَدًا وَقَدْ حَانَ وِلاَدُهَا - فَأَخْرَجْتُهَا إِلَيْهِمَا فَقَالاَ نَاوِلْنَاهَا فَرَفَعْتُهَا إِلَيْهِمَا فَجَعَلاَهَا مَعَهُمَا عَلَى بَعِيرِهِمَا ثُمَّ انْطَلَقَا .
