Messenger of Allah ﷺ used to offer the Fajr prayer and some believing women covered with their veiling sheets used to attend the Fajr prayer with him and then they would return to their homes unrecognized . (Using translation from Bukhārī 372)
أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتْ لَقَدْ كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي صَلَاةَ الْفَجْرِ فَيَشْهَدُهَا مَعَهُ النِّسَاءُ مِنَ الْمُؤْمِنَاتِ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ ثُمَّ يَرْجِعْنَ إِلَى بُيُوتِهِنَّ وَمَا يَعْرِفُهُنَّ أَحَدٌ مِنَ النَّاسِ
