It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him), and Sharik narrates it as marfu', that he (peace and blessings be upon him) said: "There is no sin upon a person in marrying for a little or a lot of wealth, when they are mutually agreed and have taken witnesses."
Abu Harun al-Abdi is not used as evidence, and it has also been narrated as marfu' from Abu Sa'id through another weak chain.
Imam al-Shafi'i (may Allah have mercy on him) said: It has reached us that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said that one may marry for three handfuls of raisins, that is, as the dowry.
