“The Messenger of Allah would not have examined (the women) except for the Ayah in which Allah said: When believing come to you pledging to you.” Ma’mar said: “Ibn Tawus informed me from his father who said: ‘The hand of the Messenger of Allah did not touch the hand of a women he had not acquired.’”  

Abū ʿĪsá said that this Ḥadīth is Ḥasan-Ṣaḥīḥ.
