Abu Dharr reported the Prophet as saying,
“If any man has camels, cattle, or sheep on which he does not pay what is due, they will be produced as large and fat as can be on the day of resurrection and will trample him with their hoofs and gore him with their horns. As often as the last of them pass him the first of them will be brought back to him until judgment is pronounced among mankind.”
وَعَنْ عَبْدُ اللَّهِ بْنِ أَبِي أَوْفَى رَضِيَ اللَّهُ عَنْهُمَا قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا أَتَاهُ قَوْمٌ بِصَدَقَتِهِمْ قَالَ: «اللَّهُمَّ صلى على آل فلَان» . فَأَتَاهُ أبي بِصَدَقَتِهِ فَقَالَ: «اللَّهُمَّ صلى الله على آل أبي أوفى»
وَفِي رِوَايَة: " إِذا أَتَى الرجل النَّبِي بِصَدَقَتِهِ قَالَ: «اللَّهُمَّ صلي عَلَيْهِ»
‘Abdallah b. Abu Aufa told that the Prophet said when people brought him their sadaqa, “O God, bless the family of so and so.” He told how, when his father brought him his sadaqa, he said, “O God, bless the family of Abu Aufa.”

He reported God s messenger as saying,
“If God gives anyone property and he does not pay the zakat on it, his property will be made to appear to him on the day of resurrection as a large bald snake with black spots over its eyes. It will be put round his neck on the day of resurrection, then seize his lihzamatani, i.e. his jaws, then say, ‘I am your property; I am your treasure’.”
He then recited, “Let not those who are niggardly think…”*
