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 .  

لَقَدْ كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي الْفَجْرَ فَيَشْهَدُ مَعَهُ نِسَاءٌ مِنَ الْمُؤْمِنَاتِ مُتَلَفِّعَاتٍ فِي مُرُوطِهِنَّ ثُمَّ يَرْجِعْنَ إِلَى بُيُوتِهِنَّ مَا يَعْرِفُهُنَّ أَحَدٌ  

The believing women covered with their veiling sheets used to attend the Fajr prayer with Allah's Apostle, and after finishing the prayer they would return to their home and nobody could recognize them because of darkness.  

كُنَّ نِسَاءُ الْمُؤْمِنَاتِ يَشْهَدْنَ مَعَ رَسُولِ اللَّهِ ﷺ صَلاَةَ الْفَجْرِ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ ثُمَّ يَنْقَلِبْنَ إِلَى بُيُوتِهِنَّ حِينَ يَقْضِينَ الصَّلاَةَ لاَ يَعْرِفُهُنَّ أَحَدٌ مِنَ الْغَلَسِ  

The believing women observed the morning prayer with the Messenger of Allah ﷺ wrapped in their mantles. They then went back to their houses and were unrecognisable, because of the Messenger of Allah's ﷺ praying in the darkness before dawn.  

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتْ لَقَدْ كَانَ نِسَاءٌ مِنَ الْمُؤْمِنَاتِ يَشْهَدْنَ الْفَجْرَ مَعَ رَسُولِ اللَّهِ ﷺ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ ثُمَّ يَنْقَلِبْنَ إِلَى بُيُوتِهِنَّ وَمَا يُعْرَفْنَ مِنْ تَغْلِيسِ رَسُولِ اللَّهِ ﷺ بِالصَّلاَةِ  

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
