However, Ibn Maʿīn and Ibn ʿAdī have stated that he was among the weak transmitters. Ibn Ḥibbān, on the other hand, counted him among the trustworthy transmitters. Zubayr b. Bakkār also mentioned him, praising his leadership and nobility.
In summary, what we can say is this:
Nafīsa, the daughter of Abū Muḥammad Ḥasan b. Zayd, went to Egypt with her husband Muʾtaman Isḥāq b. Jaʿfar and settled there. She was wealthy. She did good to people, to those afflicted with leprosy, to the crippled, to the sick, and in short, to everyone. She was a devout, ascetic, and very charitable woman.
When Imām Shāfiʿī came to Egypt, Nafīsa also showed him generosity. During the month of Ramadan, he would often pray behind her. When Imām Shāfiʿī passed away, Nafīsa requested that his funeral be brought to her house; the funeral was brought to her house, and she prayed over him there. When she herself passed away, her husband Isḥāq b. Jaʿfar wanted to take her to the Prophet's city, Medina, but the people of Egypt prevented him from doing so and insisted that Nafīsa be buried in Egypt, among them. She was buried in her house in the neighborhood known as Darb al-Sibāʿ, between old Cairo and Egypt. According to Ibn Khallikān, Sayyida Nafīsa died in the month of Ramadan in the year 208 of the Hijra. The people of Egypt believed that she was a woman endowed with karāma (a saintly wonder).
I say: Up to now, the people have held truly many erroneous beliefs about Sayyida Nafīsa and others. Especially the people of Egypt have used ugly expressions about Sayyida Nafīsa that could lead a person to kufr (disbelief) and shirk (associating partners with God). In fact, they should know that it is not permissible to use such expressions.
Some have also claimed that Sayyida Nafīsa was from the lineage of Zayn al-ʿĀbidīn;
but she is not from his lineage. What should be believed about her is what should be believed about other righteous women. Indeed, the origin of idolaters worshipping idols is their holding exaggerated and baseless beliefs about graves and those buried in them. The Prophet (peace and blessings be upon him) commanded that graves be leveled and flattened. It is forbidden to use exaggerated expressions and to believe that people possess extraordinary powers. To believe that a person can benefit or harm another apart from Allah's will is shirk. Whoever holds this belief is a mushrik (one who commits shirk). May Allah have mercy on Sayyida Nafīsa. May He elevate her station.
