What is the ruling on a female student uncovering her face in front of a teacher who is blind?

Question:
The questioner says: In some girls' secondary schools, the Qur'an teacher is a blind man, and the students are forced to uncover their faces to read. What is the ruling on this? Knowing that some people demand that the man not be present. Please give us a ruling, and may Allah reward you.

Answer:
There is no doubt that keeping men away from women is safer, more complete, and further from fitnah (trial, discord or temptation). Therefore, it is obligatory for those responsible for teaching girls to pay attention to this. However, if there is a pressing need for a blind man to teach them, the need has a ruling, but one must choose for this role someone whose religion, trustworthiness, and knowledge are reliable, so that the danger of fitnah is avoided.
As for the issue of a woman uncovering her face in the presence of a blind man, this is a matter of scholarly disagreement. Some scholars hold that she must cover her face just as she covers it from a sighted man. Their evidence is that when a blind man entered upon the Prophet (peace and blessings be upon him) while his wives were present, he ordered them to veil themselves from him. They said, "He is blind." He said (peace and blessings be upon him), "Are you both blind?" This is their evidence.
The second opinion is that there is no harm in a woman uncovering her face in the presence of a blind man, because he cannot see her. The Prophet (peace and blessings be upon him) said: Yes.
He also said to Fatimah bint Qays, or another divorced woman who was in 'iddah (the waiting period after divorce or widowhood) with Ibn Umm Maktum, "He is a blind man, so you may remove your clothes in his presence," or something similar to what the Prophet (peace and blessings be upon him) said. They said this is evidence that it is not obligatory to cover the face from a blind man. They say this is the stronger position, having a more authentic chain of narration than the first hadith. In any case, avoiding what leads to fitnah is undoubtedly required.
