Musnad Abi Ya'la 55 — : I went out with two (silver) anklets to sell

It is narrated from Sayyiduna Abu Rafi' (may Allah be pleased with him) that: I went out with two (silver) anklets to sell them, because my family needed money for their expenses. Meanwhile I met Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him), and he asked: "Where are you heading?" I said: My family has come to need money for expenses, so I want to sell these two anklets. He said: "I too have come out with a few dirhams, to obtain with them silver better than them." The narrator said: He put the anklets in one pan of the scales and the dirhams in the other pan, and the anklets came out somewhat heavier than the dirhams, so he called for a pair of shears. I said (offering it as a gift): "Subhan Allah (Glory be to Allah)! This (extra weight) is yours, it is yours." Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: "If you leave it (without an equal exchange), Allah Almighty will not leave it (that is, He will call it to account), for I heard the Messenger of Allah (peace and blessings be upon him) say: 'Gold for gold, like for like, and silver for silver, like for like (is to be sold); the one who gives more and the one who asks for more are both in the Fire.'"
