Concerning Allah's statement,

[فِى يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ]

(in a Day the measure whereof is fifty thousand years.) This refers to the Day of Judgement. Ibn Abi Hatim recorded from Ibn `Abbas that he said concerning the Ayah,

[فِى يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ]

(in a Day the measure whereof is fifty thousand years.) "It is the Day of Judgement.'' The chain of narration of this report (to Ibn `Abbas) is authentic. Ath-Thawri reported from Simak bin Harb from `Ikrimah that he said concerning this verse, "It is the Day of Judgement.'' Ad-Dahhak and Ibn Zayd both said the same. `Ali bin Abi Talhah reported from Ibn `Abbas concerning the Ayah,

[تَعْرُجُ الْمَلَـئِكَةُ وَالرُّوحُ إِلَيْهِ فِى يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ ]

(The angels and the Ruh ascend to Him in a Day the measure whereof is fifty thousand years.) "It is the Day of Judgement that Allah has made to be the measure of fifty thousand years for the disbelievers. '' Many Hadiths have been reported with this same meaning. Imam Ahmad recorded from Abu `Umar Al-Ghudani that he said, "I was with Abu Hurayrah when a man from Bani `Amir bin Sa`sa`ah passed and it was said: `This man is the wealthiest man of Bani `Amir.' So Abu Hurayrah said, `Bring him back to me.' So they brought the man back to Abu Hurayrah. Then Abu Hurayrah said, `I have been informed that you are a man of great wealth.' The man from Bani `Amir replied, `Yes, by Allah. I have one hundred red-colored camels, one hundred brown-colored camels...' and so on he counted numerous colored camels, the races of the slaves and the types of fetters for his horses that he owned. So Abu Hurayrah said, `Beware of the hooves of the camels and the cloven hooves of the cattle.' He continued repeating that to him until the color of the man began to change. Then the man said, `O Abu Hurayrah what is this' Abu Hurayrah replied, `I heard the Messenger of Allah say,

«مَنْ كَانَتْ لَهُ إِبِلٌ لَا يُعْطِي حَقَّهَا فِي نَجْدَتِهَا وَرِسْلِهَا»

(Whoever has camels and does not give their due (Zakah) in their Najdah and their Risl...) We interrupted saying, `O Messenger of Allah! What is their Najdah and Risl' He said,

«فِي عُسْرِهَا وَيُسْرِهَا، فَإِنَّهَا تَأْتِي يَوْمَ الْقِيَامَةِ كَأَغَذِّ مَا كَانَتْ وَأَكْثَرِهِ وَأَسْمَنِهِ وَآشَرِهِ، ثُمَّ يُبْطَحُ لَهَا بِقَاعٍ قَرْقَرٍ فَتَطَؤُهُ بِأَخْفَافِهَا، فَإِذَا جَاوَزَتْهُ أُخْرَاهَا أُعِيدَتْ عَلَيْهِ أُولَاهَا فِي يَوْم كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ، حَتْى يُقْضَى بَيْنَ النَّاسِ فَيَرَى سَبِيلَهُ. وَإِذَا كَانَتْ لَهُ بَقَرٌ لَا يُعْطِي حَقَّهَا فِي نَجْدَتِهَا وَرِسْلِهَا، فَإِنَّهَا تَأْتِي يَوْمَ الْقِيَامَةِ كَأَغَذِّ مَا كَانَتْ وَأَكْثَرِهِ وَأَسْمَنِهِ وَآشَرِهِ،ثُمَّ يُبْطَحُ لَهَا بِقَاعٍ قَرْقَرٍ، فَتَطَؤُهُ كُلُّ ذَاتِ ظِلْفٍ بِظِلْفِهَا وَتَنْطَحُهُ كُلُّ ذَاتِ قَرْنٍ بِقَرْنِهَا، لَيْسَ فِيهَا عَقْصَاءُ وَلَا عَضْبَاءُ، إِذَا جَاوَزَتْهُ أُخْرَاهَا أُعِيدَتْ عَلَيْهِ أُولَاهَا، فِي يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ حَتْى يُقْضَى بَيْنَ النَّاسِ فَيَرَى سَبِيلَهُ. وَإِذَا كَانَتْ لَهُ غَنَمٌ لَا يُعْطِي حَقَّهَا فِي نَجْدَتِهَا وَرِسْلِهَا فَإِنَّهَا تَأْتِي يَوْمَ الْقِيَامَةِ كَأَغَذِّ مَا كَانَتْ وَأَسْمَنِهِ وَآشَرِهِ حَتْى يُبْطَحَ لَهَا بِقَاعٍ قَرْقَرٍ فَتَطَؤُهُ كُلُّ ذَاتِ ظِلْفٍ بِظِلْفِهَا وَتَنْطَحُهُ كُلُّ ذَاتِ قَرْنٍ بِقَرْنِهَا، لَيْسَ فِيهَا عَقْصَاءُ وَلَا عَضْبَاءُ إِذَا جَاوَزَتْهُ أُخْرَاهَا أُعِيدَتْ عَلَيْهِ أُولَاهَا، فِي يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ، حَتْى يُقْضَى بَيْنَ النَّاسِ فَيَرَى سَبِيلَه»

(It is their difficulty and their ease, for verily, they will come on the Day of Resurrection healthier than before. They will be more in number, fatter and more lively and unruly. Then a soft, level plain will be spread out for them and they will trample him with their hooves. When the last of them has passed over him, the first of them will return to trample him again during a day whose measure will be fifty thousand years. This will continue until the case of all the people is decided between them. Then he (the withholder of Zakah) will see his path (i.e., either to Paradise or Hell). If he had cows that he did not pay the Zakah in their ease and their difficult times, then they will come on the Day of Judgement healthier than they were before. They will be more in number, fatter and more lively and unruly. Then a soft, level plain will be spread out for them and they will trample him. Every one of them that has cloven hooves will trample him with its hooves, and every one of them that has a horn will butt him with its horn. There will not be any hornless or bent horned animals among them. When the last of them has passed over him, the first of them will return to trample him again during a day whose measure will be fifty thousand years. This will continue until the case of all the people is decided between them. Then he (the withholder of Zakah) will see his path (i.e., either to Paradise or Hell). If he has any sheep that he does not pay the due Zakah in their difficulty and their ease, then they will come on the Day of Judgement healthier than they were before. They will be more (in number) fatter and more lively and unruly. Then a soft, level plain will be spread out for them and they will trample him. Every one of them that has a cloven hoof will trample him with its hooves, and every one of them that has a horn will butt him with its horn. There will not be any hornless or bent horned animals among them. When the last of them has passed over him, the first of them will return to trample him again during a day whose measure will be fifty thousand years. This will continue until the case of all the people is decided between them. Then he (the withholder of Zakah) will see his path (i.e., either to Paradise or Hell).) Then, the man from Bani `Amir said, `What is the due of the camel, O Abu Hurayrah' Abu Hurayrah said, `It is that you give (in your Zakah payment) from your most valuable camels, that you lend a milking she-camel, that you lend your mount for riding, that you give the milk (to the people) for drinking, and you lend the male camel for breeding.''' This Hadith was also recorded by Abu Dawud and An-Nasa'i.
