Sunan an-Nasa'i, Volume 3, Book 23, Hadith 2460 (DarusSalam) ⓘ

It was narrated from wa'il bin Hujr that: 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)

أَخْبَرَنَا هَارُونُ بْنُ زَيْدِ بْنِ يَزِيدَ، - يَعْنِي ابْنَ أَبِي الزَّرْقَاءِ - قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا سُفْيَانُ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِيهِ، عَنْ وَائِلِ بْنِ حُجْرٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم بَعَثَ سَاعِيًا فَأَتَى رَجُلاً فَأَتَاهُ فَصِيلاً مَخْلُولاً فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ 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 عَزَّ وَجَلَّ وَإِلَى نَبِيِّهِ صلى الله عليه وسلم ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ اللَّهُمَّ بَارِكْ فِيهِ وَفِي إِبِلِهِ ‏"‏ ‏.‏
