Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever makes a cash transaction regarding something, then he should not make any change in what is given as payment." Ibrahim bin Sa'id says: That is, he should receive the very thing for which he made the cash transaction, or he should pay the very compensation upon which he made the cash transaction.
