Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) married an Ansari woman, so the Noble Prophet (peace and blessings be upon him) asked him: How much did you give her as mahr (dowry)? He replied: I gave her gold equal to the weight of a date stone. Ibn Abi Najih says: "Nawah" refers to five dirhams, "Nash" to twenty dirhams, and "Uqiyyah" to forty dirhams.
