Narrated Khalid bin Aslam: 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."

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.' "
