‘Umm Athiyah reported the Prophet ﷺ as saying “A woman must not observe mourning for more than three (days) except for four months and ten days in the case of a husband and she must not wear a dyed garment except one of the types made of dyed yarn or apply collyrium or touch perfume except for a little costus or azfar when she has been purified after her menstrual courses. The narrator Ya’qub mentioned the words “except washed clothes” instead of the words “one of the types made of dyed yarn”. Ya’qub also added “She must not apply Henna” (Using translation from Abū Dāʾūd 2302)
رَسُولَ اللهِ ﷺ نَهَى أَنْ تُحِدَّ الْمَرْأَةُ فَوْقَ ثَلَاثَةِ أَيَّامٍ إِلَّا عَلَى زَوْجٍ فَإِنَّهَا تُحِدُّ عَلَيْهِ أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا وَلَا تَلْبَسُ ثَوْبًا مَصْبُوغًا إِلَّا ثَوْبَ عَصَبٍ وَلَا تَكْتَحِلُ وَلَا تَمَسُّ طِيبًا إِلَّا إِلَى أَدْنَى طُهْرَتِهَا إِذَا طَهُرَتْ بِنُبْذَةٍ مِنْ قُسْطٍ أَوْ أَظْفَارٍ
