"The time of waiting for Nifas during the time of AIlah's Messenger was forty days. We used to cover our faces with reddish-brown Wars." (Using translation from Tirmidhī 139)
«كَانَتِ النُّفَسَاءُ تَجْلِسُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ أَرْبَعِينَ يَوْمًا أَوْ أَرْبَعِينَ لَيْلَةً فَكَانَتْ إِحْدَانَا تَطْلِي الْوَرْسَ عَلَى وَجْهِهَا مِنَ الْكَلَفِ»
