Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: A man came to the service of the Prophet (peace and blessings be upon him) and said: I have married a woman. The Prophet (peace and blessings be upon him) asked: How much dowry did you give her? He replied: Four uqiyah. The Prophet (peace and blessings be upon him) said: Four uqiyah is as if you have searched for silver equal to the width of this mountain.
