Sayyiduna Abu Hadrad al-Aslami (may Allah be pleased with him) narrates: "I came to the Messenger of Allah (peace and blessings be upon him), having just married, and he (peace and blessings be upon him) asked: 'O Abu Hadrad, how much dowry (mahr) did you give?'" I said: "Five uqiyahs." So the Messenger of Allah (peace and blessings be upon him) said to me: "Even if you were scooping (wealth) by the handful from (the valley of) Buthan, you would not give more than this."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Zayd bin Aslam except Umar bin Suhban, and Umar bin Sahl is alone in narrating it."
"And the well-known version is the one that Yahya bin Sa'id al-Ansari (may Allah have mercy on him) narrated from Muhammad bin Ibrahim al-Taymi (may Allah have mercy on him), from Sayyiduna Abu Hadrad (may Allah be pleased with him)."
