We went out with 'Abdullah bin 'Umar and a bedouin said (to 'Abdullah), "Tell me about Allah's saying: "And those who hoard up gold and silver (Al-Kanz - money, gold, silver etc., the Zakat of which has not been paid) and spend it not in the Way of Allah (V.9:34)." Ibn 'Umar said, "Whoever hoarded them and did not pay the Zakat thereof, then woe to him. But these holy Verses were revealed before the Verses of Zakat. So when the Verses of Zakat were revealed, Allah made Zakat a purifier of the property."  

أَخْبِرْنِي قَوْلَ اللَّهِ {وَالَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ وَلاَ يُنْفِقُونَهَا فِي سَبِيلِ اللَّهِ} قَالَ ابْنُ عُمَرَ ؓ مَنْ كَنَزَهَا فَلَمْ يُؤَدِّ زَكَاتَهَا فَوَيْلٌ لَهُ إِنَّمَا كَانَ هَذَا قَبْلَ أَنْ تُنْزَلَ الزَّكَاةُ فَلَمَّا أُنْزِلَتْ جَعَلَهَا اللَّهُ طُهْرًا لِلأَمْوَالِ  

Messenger of Allah ﷺ said, "No Zakat is due on property mounting to less than five Uqiyas (of silver), and no Zakat is due on less than five camels, and there is no Zakat on less than five Wasqs." (A Wasqs equals 60 Sa's) & (1 Sa=3 K gms App.)  

أَنَّهُ سَمِعَ أَبَا سَعِيدٍ ؓ يَقُولُ قَالَ النَّبِيُّ ﷺ لَيْسَ فِيمَا دُونَ خَمْسِ أَوَاقٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسِ ذَوْدٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسِ أَوْسُقٍ صَدَقَةٌ  

I passed by a place called Ar-Rabadha and by chance I met Abu Dhar and asked him, "What has brought you to this place?" He said, "I was in Sham and differed with Muawiya on the meaning of (the following verses of the Qur'an): 'They who hoard up gold and silver and spend them not in the way of Allah.' (9.34). Muawiya said, 'This verse is revealed regarding the people of the scriptures." I said, It was revealed regarding us and also the people of the scriptures." So we had a quarrel and Mu'awiya sent a complaint against me to ʿUthman. ʿUthman wrote to me to come to Medina, and I came to Medina. Many people came to me as if they had not seen me before. So I told this to ʿUthman who said to me, "You may depart and live nearby if you wish." That was the reason for my being here for even if an Ethiopian had been nominated as my ruler, I would have obeyed him .  

مَرَرْتُ بِالرَّبَذَةِ فَإِذَا أَنَا بِأَبِي ذَرٍّ ؓ فَقُلْتُ لَهُ مَا أَنْزَلَكَ مَنْزِلَكَ هَذَا قَالَ كُنْتُ بِالشَّأْمِ فَاخْتَلَفْتُ أَنَا وَمُعَاوِيَةُ فِي الَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ وَلاَ يُنْفِقُونَهَا فِي سَبِيلِ اللَّهِ قَالَ مُعَاوِيَةُ نَزَلَتْ فِي أَهْلِ الْكِتَابِ فَقُلْتُ نَزَلَتْ فِينَا وَفِيهِمْ فَكَانَ بَيْنِي وَبَيْنَهُ فِي ذَاكَ وَكَتَبَ إِلَى عُثْمَانَ ؓ يَشْكُونِي فَكَتَبَ إِلَىَّ عُثْمَانُ أَنِ اقْدَمِ الْمَدِينَةَ فَقَدِمْتُهَا فَكَثُرَ عَلَىَّ النَّاسُ حَتَّى كَأَنَّهُمْ لَمْ يَرَوْنِي قَبْلَ ذَلِكَ فَذَكَرْتُ ذَاكَ لِعُثْمَانَ فَقَالَ لِي إِنْ شِئْتَ تَنَحَّيْتَ فَكُنْتَ قَرِيبًا فَذَاكَ الَّذِي أَنْزَلَنِي هَذَا الْمَنْزِلَ وَلَوْ أَمَّرُوا عَلَىَّ حَبَشِيًّا لَسَمِعْتُ وَأَطَعْتُ  

While I was sitting with some people from Quraish, a man with very rough hair, clothes, and appearance came and stood in front of us, greeted us and said, "Inform those who hoard wealth, that a stone will be heated in the Hell-fire and will be put on the nipples of their breasts till it comes out from the bones of their shoulders and then put on the bones of their shoulders till it comes through the nipples of their breasts the stone will be moving and hitting." After saying that, the person retreated and sat by the side of the pillar, I followed him and sat beside him, and I did not know who he was. I said to him, "I think the people disliked what you had said." He said, "These people do not understand anything, although my friend told me." I asked, "Who is your friend?" He said, "The Prophet ﷺ said (to me), 'O Abu Dhar! Do you see the mountain of Uhud?' And on that I (Abu Dhar) started looking towards the sun to judge how much remained of the day as I thought that Messenger of Allah ﷺ wanted to send me to do something for him and I said, 'Yes!' He said, 'I do not love to have gold equal to the mountain of Uhud unless I spend it all (in Allah's cause) except three Dinars (pounds). These people do not understand and collect worldly wealth. No, by Allah, Neither I ask them for worldly benefits nor am I in need of their religious advice till I meet Allah, The Honorable, The Majestic." '
