Sayyiduna Ali (may Allah be pleased with him) said: The hand is not to be cut off except for ten dirhams, and the dowry (mahr) is not less than ten dirhams.
This chain combines unknown (majhul) and weak (da'if) narrators. As for the hadith of Ibn Mas'ud (may Allah be pleased with him), it is munqati' (disconnected); it has been narrated from Abu Hanifah, from al-Qasim bin Abd al-Rahman, from his father, from Ibn Mas'ud, but al-Mas'udi differed from him and narrated it mursal, as has passed, and what has been narrated in opposition to it is not weaker than it.
