Allah said,
﴿وَالَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ وَلاَ يُنفِقُونَهَا فِي سَبِيلِ اللَّهِ فَبَشِّرْهُمْ بِعَذَابٍ أَلِيمٍ﴾
(And those who hoard ﴿Kanz﴾ gold and silver and spend them not in the way of Allah, announce unto them a painful torment.) ﴿9:34﴾. This is the third category of leaders, for people rely on their scholars, worshippers and the wealthy among them. When these categories of people become corrupt, the society in general becomes corrupt. Ibn Al-Mubarak once said, "What corrupted the religion, except kings and wicked Ahbar and Ruhban.'' As for Kanz, it refers to the wealth on which Zakah has not been paid, according to Malik, who narrated this from `Abdullah bin Dinar from Ibn `Umar. Al-Bukhari recorded that Az-Zuhri said that Khalid bin Aslam said that `Abdullah bin `Umar said, "This was before Zakah was ordained. When Zakah was ordained, Allah made it a cleanser for wealth.'' `Umar bin `Abdul-`Aziz and `Irak bin Malik said that this Ayah was abrogated by Allah's statement,
﴿خُذْ مِنْ أَمْوَلِهِمْ صَدَقَةً﴾
(Take Sadaqah (alms) from their wealth) There are many Hadiths that admonish hoarding gold and silver. We will mention here some of these Hadiths. `Abdur-Razzaq recorded a Hadith from `Ali about Allah's statement,
﴿وَالَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ﴾
(And those who hoard up gold and silver...) `Ali said that the Prophet said,
« تَبًّا لِلذَّهَبٍ تَبًّا لِلْفِضَّة»
(Woe to gold! Woe to silver.) He repeated this statement thrice, and this Hadith was hard on the Companions of the Messenger of Allah , who said, "What type of wealth should we use'' `Umar said, "I will find out for you,'' and he asked, "O Allah's Messenger! Your statement was hard for your Companions. They asked, `What wealth should we use''' The Prophet answered,
«لِسَانًا ذَاكِرًا وَقَلْبًا شَاكِرًا وَزَوْجَةً تُعِينُ أَحَدَكُمْ عَلَى دِينِه»
(A remembering tongue, an appreciative heart and a wife that helps one of you implement his religion.) Allah's statement,
﴿يَوْمَ يُحْمَى عَلَيْهَا فِى نَارِ جَهَنَّمَ فَتُكْوَى بِهَا جِبَاهُهُمْ وَجُنوبُهُمْ وَظُهُورُهُمْ هَـذَا مَا كَنَزْتُمْ لأَنفُسِكُمْ فَذُوقُواْ مَا كُنتُمْ تَكْنِزُونَ ﴾
(On the Day when that will be heated in the fire of Hell and with it will be branded their foreheads, their flanks, and their backs, (and it will be said unto them) "This is the treasure which you hoarded for yourselves. Now taste of what you used to hoard.'') These words will be said to them as a way of admonishing, criticizing and mocking them. Allah also said;
﴿ثُمَّ صُبُّواْ فَوْقَ رَأْسِهِ مِنْ عَذَابِ الْحَمِيمِ - ذُقْ إِنَّكَ أَنتَ الْعَزِيزُ الْكَرِيمُ ﴾
(Then pour over his head the torment of boiling water. "Taste you (this)! Verily, you were (pretending to be) the mighty, the generous!'') ﴿44:48-49﴾. There is a saying that goes, "He who covets a thing and prefers it to Allah's obedience, will be punished with it.'' Because hoarding money was better to these people than Allah's pleasure, they were punished with it. For instance, Abu Lahab, may Allah curse him, was especially active in defying the Messenger of Allah , and his wife was helping him in this regard. Therefore, on the Day of Resurrection, she will help in punishing him, for there will be a twisted rope of palm fiber on her neck. She will be gathering wood from the Fire and throwing it on him so that his torment is made harder by the hand of someone whom he used to care for in this life. Likewise, money was precious to those who hoarded it in this life. Therefore, money will produce the worst harm for them in the Hereafter, when it will be heated in the Fire of Jahannam, whose heat is quiet sufficient, and their forehead, sides and back will be branded with it. Imam Abu Ja`far Ibn Jarir recorded that Thawban said that the Messenger of Allah used to declare,
«مَنْ تَركَ بَعْدَهُ كَنْزًا مُثِّلَ لَهُ يَوْمَ الْقِيَامَةِ شُجَاعًا أَقَرَعَ لَهُ زَبِيبَتَانِ يَتْبَعُهُ وَيَقُولُ: وَيْلَكَ مَا أَنْتَ؟ فَيَقُولُ: أَنَا كَنْزُكَ الَّذِي تَرَكْتَهُ بَعْدكَ وَلَا يَزَالُ يَتْبَعُهُ حَتَّى يُلْقِمَهُ يَدَهُ فَيَقْضِمَهَا ثُمَّ يَتْبَعُهَا سَائِرَ جَسَدِه»
(Whoever leaves a treasure behind (on which he did not pay the Zakah), then on the Day of Resurrection his wealth will be made like a bald-headed poisonous male snake with two black spots over the eyes. The snake will follow him, and he will say, `Woe to you! Who are you' The snake will say, `I am your treasure that you left behind,' and will keep following him until the man gives it his hand; the snake will devour it and then devour his whole body.) Ibn Hibban also collected this Hadith in his Sahih. Part of this Hadith was also collected in the Two Sahihs from Abu Hurayrah. In his Sahih, Muslim recorded from Abu Hurayrah that the Messenger of Allah said,
«مَا مِنْ رَجُلٍ لَا يُؤَدِّي زَكَاةَ مَالِهِ إِلَّا جُعِلَ لَهُ يَوْمَ الْقِيَامَةِ صَفَائِحُ مِنْ نَارٍ، فَيُكْوَى بِهَا جَنْبُهُ وَجَبْهَتُهُ وَظَهْرُهُ فِي يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ، حَتَّى يُقْضَى بَيْنَ الْعِبَادِ ثُمَّ يُرَى سَبِيلُهُ إِمَّا إِلَى الْجَنَّةِ وَإِمَّا إِلَى النَّار»
(Every man who does not pay the Zakah due on his money, then on the Day of Resurrection, his side, forehead and back will be branded with rods made of fire on a Day the length of which is fifty thousand years, until when the servants will be judged; that man will be shown his destination, either to Paradise or the Fire.) aIn the Tafsir of this Ayah, Al-Bukhari recorded that Zayd bin Wahb said, "I passed by Abu Dharr in the area of Rabadhah and asked him, `What made you reside in this area' He said, `We were in Ash-Sham when I recited this Ayah,
﴿وَالَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ وَلاَ يُنفِقُونَهَا فِي سَبِيلِ اللَّهِ فَبَشِّرْهُمْ بِعَذَابٍ أَلِيمٍ﴾
(And those who hoard up gold and silver and spend them not in the way of Allah, announce unto them a painful torment.) Mu`awiyah said, `This Ayah is not about us, it is only about the People of the Book.' So I (Abu Dharr) said, `Rather, it is about us and them.''
﴿إِنَّ عِدَّةَ الشُّهُورِ عِندَ اللَّهِ اثْنَا عَشَرَ شَهْراً فِي كِتَـبِ اللَّهِ يَوْمَ خَلَقَ السَّمَوَت وَالاٌّرْضَ مِنْهَآ أَرْبَعَةٌ حُرُمٌ ذلِكَ الدِّينُ الْقَيِّمُ فَلاَ تَظْلِمُواْ فِيهِنَّ أَنفُسَكُمْ وَقَاتِلُواْ الْمُشْرِكِينَ كَآفَّةً كَمَا يُقَـتِلُونَكُمْ كَآفَّةً وَاعْلَمُواْ أَنَّ اللَّهَ مَعَ الْمُتَّقِينَ ﴾
(36. Verily, the number of months with Allah is twelve months (in a year), so was it ordained by Allah on the Day when He created the heavens and the earth; of them four are sacred. That is the right religion, so wrong not yourselves therein, and fight against the Mushrikin idolaters collectively as they fight against you collectively. But know that Allah is with those who have Taqwa.)
