عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا رَفَعَهُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّ النُّفَسَاءَ وَالْحَائِضَ تَغْتَسِلُ، وَتُحْرِمُ، وَتَقْضِي الْمَنَاسِكَ كُلَّهَا، غَيْرَ أَنَّهَا لَا تَطُوفُ بِالْبَيْتِ حَتَّى تَطْهُرَ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: "A woman in the state of nifas (postnatal bleeding) or menstruation will perform ghusl (ritual bath) and then enter into ihram. She will perform all the rites except for the tawaf of the House of Allah. When she becomes pure, she will then perform the tawaf of the House of Allah."
