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 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  

"The women used to pray Subh with the Messenger of Allah ﷺ, wrapped in their wrappers, then they would return, and no one would recognize them because of the darkness." (Using translation from Nasāʾī 546)   

أَنَّ نِسَاءً مِنَ الْمُؤْمِنَاتِ كُنَّ يُصَلِّينَ مَعَ رَسُولِ اللهِ ﷺ الصُّبْحَ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ ثُمَّ يَرْجِعْنَ إِلَى أَهْلِهِنَّ وَمَا يَعْرِفُهُنَّ أَحَدٌ مِنَ الْغَلَسِ  

[Machine] "Indeed, there were women from among the believers who used to witness with the Messenger of Allah ﷺ the Fajr (morning) prayer, and then they would return to their homes wrapped in their cloaks, with their faces covered, so as not to be recognized."  

أَنَّ نِسَاءً مِنَ الْمُؤْمِنَاتِ كُنَّ يَشْهَدْنَ مَعَ رَسُولِ اللهِ ﷺ الصُّبْحَ ثُمَّ يَنْقَلِبْنَ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ إِلَى بُيُوتِهِنَّ مَا يُعْرَفْنَ مِنَ الْغَلَسِ  

[Machine] She said, "There were indeed women among the believers who used to pray with the Messenger of Allah ﷺ, covered in their outer garments, during the Fajr (dawn) prayer. Then they would return to their homes without being recognized due to their simplicity."  

أَنَّهَا قَالَتْ «قَدْ كُنَّ نِسَاءٌ مِنَ الْمُؤْمِنَاتِ يُصَلِّينَ مَعَ رَسُولِ اللَّهِ ﷺ مُتَلَفِّعَاتٍ بِمُرُوطِهِنَّ فِي صَلَاةِ الْفَجْرِ ثُمَّ يَرْجِعْنَ إِلَى بُيُوتِهِنَّ مَا يُعْرَفْنَ مِنَ الْغَلَسِ»  

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. (Using translation from Bukhārī 578)   

نِسَاءً مِنَ الْمُؤْمِنَاتِ كُنَّ يَشْهَدْنَ صَلَاةَ الْفَجْرِ مَعَ رَسُولِ اللهِ ﷺ مُتَلَفِّعَاتٍ فِي مُرُوطِهِنَّ ثُمَّ يَنْقَلِبْنَ إِلَى بُيُوتِهِنَّ حِينَ يَقْضِينَ الصَّلَاةَ وَلَا يَعْرِفُهُنَّ أَحَدٌ مِنَ الْغَلَسِ
