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.' "
