It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: One dinar will be for one dinar, and one dirham will be for one dirham, and there will be no increase or decrease between them. This hadith was also read by Imam Ahmad’s teacher, Abdur Rahman, from Imam Malik (may Allah have mercy on them).
