"At the time of the Messenger of Allah, women in postnatal bleeding (after childbirth) used to wait for forty days, and we used to put Wars on our faces because of freckles."  

كَانَتِ النُّفَسَاءُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ تَجْلِسُ أَرْبَعِينَ يَوْمًا وَكُنَّا نَطْلِي وُجُوهَنَا بِالْوَرْسِ مِنَ الْكَلَفِ  

"The Messenger of Allah set the time for postnatal bleeding at forty days, except for one who becomes pure before that."  

كَانَ رَسُولُ اللَّهِ ﷺ وَقَّتَ لِلنُّفَسَاءِ أَرْبَعِينَ يَوْمًا إِلاَّ أَنْ تَرَى الطُّهْرَ قَبْلَ ذَلِكَ
