I went to the Messenger of Allah ﷺ and he was sitting under the shade of the Ka'ba. As he saw me he said: By the Lord of the Ka'ba, they are the losers. I came there till I sat and I could not stay (longer) and (then) stood up. I said: Messenger of Allah, let my father, be ransom for you, who are they (the losers)? He said: They are those having a huge amount of wealth except so and so and (those who spend their wealth generously on them whom they find in front of them, behind them and on their right side and on their left side) and they are a few. And no owner of camels, or cattle or goat and sheep, who does not pay Zakat (would be spared punishment) but these (camels, cattle, goats and sheep) would come on the Day of Resurrection wearing more flesh and would gore him with their horns and trample them with their hooves. And when the last one would pass away, the first one would return (to trample him) till judgment would be pronounced among people. (Using translation from Muslim 990a)   

انْتَهَيْتُ إِلَى النَّبِيِّ ﷺ وَهُوَ جَالِسٌ فِي ظِلِّ الْكَعْبَةِ فَلَمَّا رَآنِي قَالَ هُمُ الْأَخْسَرُونَ وَرَبِّ الْكَعْبَةِ قَالَ فَجِئْتُ حَتَّى جَلَسْتُ فَلَمْ أَتَقَارَّ أَنْ قُمْتُ فَقُلْتُ مَنْ هُمْ؟ فِدَاكَ أَبِي وَأُمِّي قَالَ هُمُ الْأَكْثَرُونَ إِلَّا مَنْ قَالَ بِالْمَالِ هَكَذَا وَهَكَذَا أَرْبَعَ مَرَّاتٍ وَقَلِيلٌ مَا هُمْ مَا مِنْ صَاحِبِ إِبِلٍ وَلَا بَقَرٍ وَلَا غَنَمٍ لَا يُؤَدِّي زَكَاتَهَا إِلَّا جَاءَتْ يَوْمَ الْقِيَامَةِ أَعْظَمَ مَا كَانَتْ وَأَسْمَنَهُ تَنْطَحُهُ بِقُرُونِهَا وَتَطَؤُهُ بِأَخْفَافِهَا كُلَّمَا نَفَذَتْ أُخْرَهَا عَادَتْ عَلَيْهِ أُولَاهَا حَتَّى يُقْضَى بَيْنَ النَّاسِ لَفْظُ حَدِيثِ وَكِيعٍ  

[Machine] On the authority of the Prophet ﷺ , he said: "If a person does not fulfill the rights of Allah, the Most High, in giving charity for his camels, they will make it stumble in a barren area, trampling on it with their hooves and biting it with their mouths, whenever its other camels pass by, it will strike it with the front until it sees its source either from Paradise or from the Hellfire. Similarly, if a person does not fulfill the rights of Allah, the Most High, in his cows, they will make it stumble in a barren area, trampling on it with their hooves and butting it with their horns, whenever its other cows pass by, it will strike it with the front until it sees its source either from Paradise or from the Hellfire. And likewise, the sheep will butt it with their horns and trample on it with their hooves until it sees its source either from Paradise or from the Hellfire. The horses have three rewards, sins, and a covering. Whoever acquires them for chastity and enrichment, they will be a covering for him. And whoever acquires them as equipment for jihad in the way of Allah, they will be a reward for him, and if he extends them honor or two honors, he will have a reward in that. And whoever acquires them to show off, boast, and scorn the Muslims, they will be a sin for him." A person asked, "What about red camels, O Messenger of Allah?" He said, "Nothing comes in red camels except for the comprehensive, decisive verse: 'So whoever does an atom's weight of good will see it. And whoever does an atom's weight of evil will see it.'" (Quran, Surah Al-Zalzalah, 99:7-8)  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا لَمْ يُؤَدِّ الْمَرْءُ حَقَّ اللهِ تَعَالَى فِي الصَّدَقَةِ فِي إِبِلِهِ بُطِحَ لَهَا بِصَعِيدٍ قَرْقَرٍ فَوَطِئَتْهُ بِأَخْفَافِهَا وَعَضَّتْهُ بِأَفْوَاهِهَا إِذَا مَرَّ عَلَيْهِ أُخْرَاهَا كرَّ عَلَيْهِ أُولَاهَا حَتَّى يَرَى مَصْدَرَهُ إِمَّا مِنَ الْجَنَّةِ وَإِمَّا مِنَ النَّارِ وَالْبَقَرُ إِذَا لَمْ يُؤَدَّ حَقُّ اللهِ تَعَالَى فِيهَا بُطِحَ لَهَا بِصَعِيدٍ قَرْقَرٍ فَوَطِئَتْهُ بِأَظْلَافِهَا وَنَطَحَتْهُ بِقُرُونِهَا إِذَا مَرَّ عَلَيْهِ أُخْرَاهَا كرَّ عَلَيْهِ أُولَاهَا حَتَّى يَرَى مَصْدَرَهُ إِمَّا مِنَ الْجَنَّةِ وَإِمَّا مِنَ النَّارِ وَالْغَنَمُ كَذَلِكَ تَنْطَحُهُ بِقُرُونِهَا وَتَطَؤُهُ بِأَظْلَافِهَا لَيْسَ فِيهَا عَقْصَاءُ وَلَا جَمَّاءُ حَتَّى يَرَى مَصْدَرَهُ إِمَّا مِنَ الْجَنَّةِ وَإِمَّا مِنَ النَّارِ وَالْخَيْلُ ثَلَاثَةٌ أَجْرٌ وَوِزْرٌ وَسِتْرٌ فَمَنِ اقْتَنَاهَا تَعَفُّفًا وَتَغَنِّيًا كَانَتْ لَهُ سِتْرًا وَمَنِ اقْتَنَاهَا عِدَّةً لِلْجِهَادِ فِي سَبِيلِ اللهِ كَانَتْ لَهُ أَجْرًا وَإِنْ طَوَّلَ لَهَا شَرَفًا أَوْ شَرَفَيْنِ كَانَ لَهُ فِي ذَلِكَ أَجْرٌ وَمَنِ اقْتَنَاهَا فَخْرًا وَرِئَاءً وَنِوَاءً عَلَى الْمُسْلِمِينَ كَانَتْ لَهُ وِزْرًا قَالَ قَائِلٌ أَرَأَيْتَ الْحُمُرَ يَا رَسُولَ اللهِ قَالَ لَمْ يَأْتِ فِي الْحُمُرِ شَيْءٌ إِلَّا الْآيَةُ الْجَامِعَةُ الْفَاذَّةُ {فَمَنْ يَعْمَلْ مِثْقَالَ ذَرَّةٍ خَيْرًا يَرَهُ وَمَنْ يَعْمَلْ مِثْقَالَ ذَرَّةٍ شَرًّا يَرَهُ } [الزلزلة 8]
