Women tore their lower garments from the corners and covered their faces with them. (Ṣaḥīḥ Bukhārī, vol. 3, pp. 290, Ḥadīš 4759)

4. Careful about veil

The wife of Abul Qu’ays breastfed the mother of the believers, Sayyidatunā ‘Āishaĥ Ṣiddīqaĥ رَضِیَ الـلّٰـهُ تَـعَـالٰی عَـنْهَا when she was a child. Therefore, Abul Qu’ays was Sayyidatunā ‘Āishaĥ Ṣiddīqaĥ’s Raḍāī^[1] father and Abul Qu’ays’s brother Aflaḥ was Sayyidatunā ‘Āishaĥ Ṣiddīqaĥ’s Raḍāī-uncle. After the blessed verses about veil were revealed, Aflaḥ intended to meet Sayyidatunā ‘Āishaĥ Ṣiddīqaĥ    رَضِیَ الـلّٰـهُ تَـعَـالٰی عَـنْهَا, but she رَضِیَ الـلّٰـهُ تَـعَـالٰی عَـنْهَا refused in view of the commandment of veil. Ṣaḥīḥ Bukhārī states: Sayyidatunā ‘Āishaĥ Ṣiddīqaĥ رَضِیَ الـلّٰـهُ تَـعَـالٰی عَـنْهَا said, ‘Let me first ask the Holy Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم whether or not I must observe veil with Aflaḥ due to a Raḍāī-relationship, because I think I drank Abul Qu’ays’s wife’s milk, but how does that make me related to Aflaḥ?’ The Prophet of Raḥmaĥ صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, ‘O ‘Āishaĥ! Allow Aflaḥ, he is your Raḍāī-uncle.’

(Ibid, pp. 306, Ḥadīš 4796)

5. Scarves must not be transparent

Sayyidunā Diḥyaĥ Bin Khalīfaĥ رَضِىَ اللهُ تَعَالٰی عَـنْهُ said: Once some white thin Egyptian cloth was brought in front of the Revered and Renowned Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. He صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم granted a piece of cloth to me as well and instructed, ‘Cut this into two pieces, use one to make a shirt for yourself and give the other to your wife to use as a scarf.’ The narrator states, ‘As I was about to leave, the Holy Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم emphasised, ‘Tell your wife to wear another cloth beneath this so that nothing is visible beneath the scarf.’ (Sunan Abī Dāwūd, vol. 4, pp. 88, Ḥadīš 4116)
