"The Zakah collector of the prophet came to us, and I went to him, sat with him, and heard him say: In my contract it says that we should not take any sucking young, nor combine what is separate, nor separate what is combined.' A man brought a she-camel with a big hump to him and said: 'Take it, but he refused." (Daif)  

أَتَانَا مُصَدِّقُ النَّبِيِّ ﷺ فَأَتَيْتُهُ فَجَلَسْتُ إِلَيْهِ فَسَمِعْتُهُ يَقُولُ إِنَّ فِي عَهْدِي أَنْ لاَ نَأْخُذَ رَاضِعَ لَبَنٍ وَلاَ نَجْمَعَ بَيْنَ مُتَفَرِّقٍ وَلاَ نُفَرِّقَ بَيْنَ مُجْتَمِعٍ فَأَتَاهُ رَجُلٌ بِنَاقَةٍ كَوْمَاءَ فَقَالَ خُذْهَا فَأَبَى  

the Prophet sent a collector and he came to a man who brought him a slim, recently-weaned camel. The Prophet said: "We sent to Zakah collector of Allah and His Messenger, and so-and-so gave him a slim, recently-weaned camel. O Allah, do not bless him nor his camels!" News of that reached the man, so he came with a beautiful she-camel and said: "I repent to Allah and to His Prophet. " The Prophet said: "O Allah, bless him and his camels!" (Daif)  

أَنَّ النَّبِيَّ ﷺ بَعَثَ سَاعِيًا فَأَتَى رَجُلاً فَأَتَاهُ فَصِيلاً مَخْلُولاً فَقَالَ النَّبِيُّ ﷺ بَعَثْنَا مُصَدِّقَ اللَّهِ وَرَسُولِهِ وَإِنَّ فُلاَنًا أَعْطَاهُ فَصِيلاً مَخْلُولاً اللَّهُمَّ لاَ تُبَارِكْ فِيهِ وَلاَ فِي إِبِلِهِ فَبَلَغَ ذَلِكَ الرَّجُلَ فَجَاءَ بِنَاقَةٍ حَسْنَاءَ فَقَالَ أَتُوبُ إِلَى اللَّهِ ﷻ وَإِلَى نَبِيِّهِ ﷺ فَقَالَ النَّبِيُّ ﷺ اللَّهُمَّ بَارِكْ فِيهِ وَفِي إِبِلِهِ
