Hazrat Urwah al-Bariqi narrates that the Noble Prophet (peace and blessings be upon him) gave him a dinar so that he could buy a goat with it. He bought two goats with that dinar, then sold one of the goats for a dinar, and brought one goat and one dinar to the Noble Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) prayed for blessing in his trade. After that, if this companion bought even soil, he would profit from it.
