Muhammad bin al-Muthna - al-Zaman محمد بن المثنى أبو موسى - الزمن · The Book of Marriage

"The Messenger of Allah forbade offering more for something that has already been bought by his brother, or for a man to propose marriage to a woman when someone else has already proposed to her, unless the previous suitor gave up the idea or gave him permission."

"I will pass the same judgment concerning her as the Messenger of Allah did. If she let you do that, I will flog you, but if she did not let you do that, I will stone you (to death)." She had let him do that so he flogged him with one hundred stripes. (One of the narrators) Qatadah said: "I wrote to Habib bin Salim and he wrote back to me with this information."
