4 – The same understanding has been handed down from some of Ibn ʿAbbās’s own students—such as Saʿīd ibn Jubayr. He explained idnāʾ (bringing down) as “placing the qināʿ (outer veil) over the khimār (head-covering)” and declared: “It is not permissible for a Muslim woman to be seen by a non-maḥram man unless the qināʿ is worn over the khimār and she has fastened it firmly around her head and throat.” This statement will appear again later in the book (p. 85).
Abū Bakr al-Jassāṣ cites much the same wording in his Aḥkām al-Qurʾān (3/372), transmitting it from Mujāhid together with Ibn ʿAbbās: “When she goes out, a free woman covers her forehead and her head.” Mujāhid was among those who learned Qurʾānic exegesis directly from Ibn ʿAbbās.
That reading was then received from Mujāhid by his pupil and transmitter Qatādah—may Allah have mercy on them all—who, commenting on idnāʾ, said: “Allah has bound them, whenever they go out, to lower the veil so that it covers the eyebrows.”
