Al-Sha'bi (may Allah have mercy on him) narrated from Qadi Shurayh (may Allah have mercy on him): It is the husband; if he wishes, he pays her the full dowry. Nafi' bin Jubayr, Muhammad bin Ka'b, Tawus, Mujahid, al-Sha'bi and Sa'id bin Jubayr said the same.
(b) Ibrahim (may Allah have mercy on him), Alqamah (may Allah have mercy on him) and al-Hasan (may Allah have mercy on him) said: It is the guardian.
(c) Amr bin Shu'ayb (may Allah have mercy on him) narrated from his father, from his grandfather (may Allah be pleased with him), that the Prophet (peace and blessings be upon him) said: "The one who holds the marriage tie is the husband."
This is not preserved (ghayr mahfuz), and Ibn Lahi'ah is not used as evidence.
