The Statement of Allah: "...And those who hoard up gold and silver (AI-Kanz—the money, the Zakãt of which has not been paid) and spend it not in the Way of Allah—announce to them a painful torment." (V.9:34) Sahih al-Bukhari 4660
Arabic hadith text
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنْ حُصَيْنٍ، عَنْ زَيْدِ بْنِ وَهْبٍ، قَالَ مَرَرْتُ عَلَى أَبِي ذَرٍّ بِالرَّبَذَةِ فَقُلْتُمَا أَنْزَلَكَ بِهَذِهِ الأَرْضِ قَالَ كُنَّا بِالشَّأْمِ فَقَرَأْتُ {وَالَّذِينَ يَكْنِزُونَ الذَّهَبَ وَالْفِضَّةَ وَلاَ يُنْفِقُونَهَا فِي سَبِيلِ اللَّهِ فَبَشِّرْهُمْ بِعَذَابٍ أَلِيمٍ} قَالَ مُعَاوِيَةُ مَا هَذِهِ فِينَا، مَا هَذِهِ إِلاَّ فِي أَهْلِ الْكِتَابِ. قَالَ قُلْتُ إِنَّهَا لَفِينَا وَفِيهِمْ.
Translation
Narrated Zaid bin Wahb
I passed by (visited ) Abu Dhar at Ar-Rabadha and said to him, "What has brought you to this land?" He said, "We were at Sham and I recited the Verse: "They who hoard up gold and silver and spend them not in the way of Allah; announce to them a painful torment, " (9.34) where upon Muawiya said, 'This Verse is not for us, but for the people of the Scripture.' Then I said, 'But it is both for us (Muslim) and for them.' "
