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  

[Machine] The Prophet ﷺ sent a message to a man, and he sent to him a worn-out, hobbling camel. The Messenger of Allah ﷺ said: "He came to him as a believer in Allah and a believer in His Messenger, so he sent to him a worn-out, hobbling camel. O Allah, do not bless him or his camels." The man received the message and sent to him a camel from his best and most beautiful camels. The Messenger of Allah ﷺ said: "Fulan has received the message of the Messenger of Allah ﷺ ." So he sent to him a camel from his best and most beautiful camels. O Allah, bless him and his camels."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ بَعَثَ إِلَى رَجُلٍ فَبَعَثَ إِلَيْهِ بِفَصِيلٍ مَخْلُولٍ فَقَالَ رَسُولُ اللهِ ﷺ جَاءَهُ مُصَدِّقُ اللهِ وَمُصَدِّقُ رَسُولِهِ فَبَعَثَ بِفَصِيلٍ مَخْلُولٍ اللهُمَّ لَا تُبَارِكْ فِيهِ وَلَا فِي إِبِلِهِ فَبَلَغَ ذَلِكَ الرَّجُلَ فَبَعَثَ إِلَيْهِ بِنَاقَةٍ مِنْ حُسْنِهَا وَجَمَالِهَا فَقَالَ رَسُولُ اللهِ ﷺ بَلَغَ فُلَانًا مَا قَالَ رَسُولُ اللهِ ﷺ فَبَعَثَ بِنَاقَةٍ مِنْ حُسْنِهَا اللهُمَّ بَارِكْ فِيهِ وَفِي إِبِلِهِ
