أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى ، عَنْ عُثْمَانَ ، عَنْ مُجَاهِدٍ ، قَالَ :" الْمَرْأَةُ الْحَائِضُ تُصَلِّي فِي ثِيَابِهَا الَّتِي تَحِيضُ فِيهَا، إِلَّا أَنْ يُصِيبَ شَيْئًا مِنْهَا دَمٌ، فَتَغْسِلَ مَوْضِعَ الدَّمِ "

Ubayd Allah ibn Musa told us, on the authority of Uthman, on the authority of Mujahid, who said: “A menstruating woman prays in the clothes in which she menstruates, unless Some of it gets blood, so you wash the place of the blood.”
