Muslim activists are on the march yet again, this time with a story about a woman who was told to leave a store on account of her not revealing her face. CAIR loves these and other types of cases as they seem so lopsided. Yet at the same time, they don’t bother to put things in the wider context. Some of these geniuses are so busy trying to neuter the Revealed Law that they missed the very principles within it that would indicate the foolishness of the whole fiasco.
Sarah Safi, 32, was told at the Gary, Indiana store that it was a high crime area and that unless she uncovered her face she would have to leave the store. When Safi meekly wondered aloud if she was going to have to leave, the attendant gave an affirmative reply. This left Safi to leave the store brokenhearted and looking for recompense.
Let’s forget the fact that Jaime, the attendant said that this is a high crime area, that these are unbelievers or any other number of mind-numbing arguments unbelievers might use. Let’s even forget the NAACP, CAIR, ADL, ACLU, ICNA and ISNA groups which really just leave one SOL in the end.
What is in the Revealed Law about this matter? What has the Lord, Blessed and Exalted be He in His Rank and Spendour, said about this matter? All of this chaos, fighting, tribulation and He has said nothing of the matter. There are no rulings of authorities? There are no statements from the jurists in this regard? What?!
Muslim women wearing complete hijab are refusing to reveal their faces for driving license photos, identification, court cases when giving evidence, airports, banks and now a convenience store. Has nothing been said? Here is the matter in full.
If there is something in the Revealed Law, then you in complete hijab are just as duty bound to observe it as the one who is not in full hijab. This issue has been brought about in many instances by yourselves and your ignorance of the Revealed Law that has been displayed. Let us look at circumstances mentioned by the legal scholars when it is permitted/mandated to uncover for the women in complete hijab.
If one has finished the rights of Hajj or Umrah (they are no longer in Ihram), they resume the niqab and gloves, but if not, they will have to wear an unattached hanging veil. When they see men coming close or passing by, they will have to veil. We will take that from the following text,
There is the hadith: Yahya related to me from Malik from Hisham ibn Urwa that Fatima bint al-Mundhir, may Allah be pleased with her, said, “We used to veil our faces when we were in Ihram in the company of Asma bint Abi Bakr As-Siddiq, may Allah be pleased with her.” 
As for the veiling while not in Ihram, Imam Ahmad mentioned the hadith from al-Hasan ibn Muslim from Safiyyah bint Shaibah that `A’ishah made tawaf while she was in niqab.
Imam Ahmad mentioned that it is permissible for a woman/man to reveal themselves to a doctor during emergency situations when needed.
Imam Muwaffaq ud-Din Ibn Qudamah, may Allah be pleased with him, explained in great depth,
“Imam Ahmad mentioned the same thing about this area as well. The basis of his understanding was the first three generations, which had taken two historical incidents into consideration. One was in the time of the Prophet, peace and blessings be upon him, when he asked Sa`d, may Allah be pleased with him, to judge in the matter of a tribe. He testified against them by looking at them and they looked at him, face to face.
There was also an incident during the khilafah of `Uthman, may Allah be pleased with him, when a man was accused of theft. He was made to come to court and look at the people and they him. The same ruling applies for buying and selling when a man looks to the face and hands of a woman for identification, transactions or testimony as what happened with the woman in the case of Rifa`ah who came wearing green clothes as mentioned in the collection of Imam Abu Dawud.” 
When the mother of the believers, `A’ishah, may Allah be pleased with her and separated from her camp and lost in the desert, she lifted her niqab as no one was around and she was searching for the way back to Madinah. Due to exhaustion, she fell asleep. When the companion Safwan adh-Dhakwani, who was sent to find her, found her sleeping and called her name, she woke up and lowered the niqab again to cover her face. 
The Messenger of Allah, peace and blessings be upon him, once married a companion to a woman and he did not look at her face or hands before they were married. He asked the companion, “Have you seen her?” He replied no. The Messenger of Allah, peace and blessings be upon him, said, “Go look in her face, for indeed the women of Quraish have something in their eyes.” Collected by Imam Muslim in his Al Jami` us-Sahih and classified as authentic. We can see from this that it is permissible to show the face but not compulsory, as the companion had trust and married without evening seeing the bride.
Female believers have to stop disgracing the Revealed Law by putting things into it that are not of it and making strictures where none exist. And we ask that Allah makes it easy for us to understand His Commands and implement them with goodness.
