وَلَمَّا دَخَلُوا۟ مِنْ حَيْثُ أَمَرَهُمْ أَبُوهُم مَّا كَانَ يُغْنِى عَنْهُم مِّنَ ٱللَّهِ مِن شَىْءٍ إِلَّا حَاجَةًۭ فِى نَفْسِ يَعْقُوبَ قَضَىٰهَا ۚ وَإِنَّهُۥ لَذُو عِلْمٍۢ لِّمَا عَلَّمْنَٰهُ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ
And when they entered in the manner which their father had enjoined, it would have naught availed them as against Allah; it was but a need of Jacob's soul which he thus satisfied; and lo! he was a lord of knowledge because We had taught him; but most of mankind know not.

Narrated Um `Atiya:
We were ordered to bring out our menstruating women and veiled women in the religious gatherings and invocation of Muslims on the two `Id festivals. These menstruating women were to keep away from their Musalla. A woman asked, "O Allah's Messenger (ﷺ) ' What about one who does not have a veil?" He said, "Let her share the veil of her companion."
