Takhrij Hadith 2153: "There were two men during…"

There were two men during the time of the Prophet (peace and blessings be upon him). One of them was a merchant, and whenever he heard the call to prayer, if the weighing scale was in his hand, he would drop it rather than set it down gently; and if it was on the ground, he would not pick it up. The other was a blacksmith who made swords for trade. Whenever his hammer was resting on the anvil, he would leave it there, and if he had raised it, he would throw it behind his back upon hearing the call to prayer. Allah, the Exalted, then revealed this as praise for both of them and for everyone who followed their example.
