Musannaf Ibn Abi Shaybah 18098 — A man who marries a woman on her own

Abd al-Malik (may Allah have mercy on him) said: A man married a woman on the basis of a dowry of his own choosing, and then he set ten dirhams as the dowry. Ata (may Allah have mercy on him) declared it permissible and said: The Muslims used to marry for less than that and for more.
