What is the meaning of the the phrase "as if crows were on their heads," and what is the opinion on Al-Albani's book "Al-Radd al-Mufhim," and does it contain hadiths that negate the obligation of covering the face and hands?

The Hadith likens the head coverings of the Ansar women, after the revelation of the verse of the Jilbab, to crows in their blackness. The book "Al-Radd al-Mufham" is a useful book on the issue of the hijab, in which the Shaykh supports the view that covering the face is not obligatory, substantiating his opinion with evidence. This issue is among the recognized matters of scholarly disagreement.
