Amrah, daughter of AbdurRahman ibn Sa’d ibn Zurarah, reported on the authority of Habibah, daughter of Sahl al-Ansariyyah: She (Habibah) was the wife of Thabit ibn Qays ibn Shimmas. The Apostle of Allah (peace_be_upon_him) came out one morning and found Habibah by his door.
The Apostle of Allah (peace_be_upon_him) said: Who is this? She replied: I am Habibah, daughter of Sahl. He asked: What is your case? She replied: I and Thabit ibn Qays, referring to her husband, cannot live together.
When Thabit ibn Qays came, the Apostle of Allah (peace_be_upon_him) said to him: This is Habibah, daughter of Sahl, and she has mentioned (about you) what Allah wished to mention.
Habibah said: Apostle of Allah, all that he gave me is with me.
