Sahih al-Bukhari 4660
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.' "
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنْ حُصَيْنٍ، عَنْ زَيْدِ بْنِ وَهْبٍ، قَالَ مَرَرْتُ عَلَى أَبِي ذَرٍّ بِالرَّبَذَةِ فَقُلْتُ مَا 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.‏
