Waail bin Hajar reported,
The Prophet ﷺ sent out a collector of zakat. The collector came to a man, and the man gave him a scrawny young camel. The Prophet ﷺ said, "We sent a collector for Allah and His Messenger, and so-and-so gave him a scrawny young camel! O Allah, do not bless him, nor his camels."When word of this reached the man, he came with a fine she-camel and said, "I repent to Allah 
and to His Prophet ﷺ."The Prophet ﷺ then said, "O Allah, bless him and his camels."

Hasanعن وائل بن حجر
أن النبي ﷺ بعث ساعيا، فأتى رجلا فآتاه فصيلا مخلولا. فقال النبي ﷺ: بعثنا مصدق الله ورسوله وإن فلانا أعطاه فصيلا مخلولا! اللهم لا تبارك فيه، ولا في إبلو. فبلغ ذلك الرجل فجاء بناقة حسناء فقال: أتوب إلى الله عز وجل وإلى نبيه ﷺ فقال النبي ﷺ: اللهم بارك فيه وفي إيله.
Nasai (2458) narrated it, and Ibn Khuzayma (2274) graded it sahih, both of them through the route of Sufyan, from Asim bin Kulayb, from his father, from Waail bin Hajar, that the Prophet ﷺ said, then he mentioned it. Its chain is hasan because of Asim bin Kulayb and his father Kulayb bin Shihab, for both of them are truthful.
