Support for the first case is the previously-cited ḥadīth of Fāṭimah bint Abī Ḥubaysh.

Evidence for the second is the ḥadīth of Umm Ḥabībah recorded by Aḥmad, mentioned a short while ago, which actually reaches back to ʿĀʾishah.

Umm Salamah also transmitted it in the Musnad (6 – 322-323, 320, 393), and it is likewise reported by Abū Dāwūd (42), N (65), Mi (199), Maj (215), and Qat (76) through the route of Sulaymān ibn Yasār on her authority. The chain is defective because of a break between him and her; Abū Dāwūd and others relate from him that “a man” informed him from her.

Nonetheless, there is another route in the Musnad (6/304): Suraij narrated to us; ʿAbd Allāh—meaning Ibn ʿUmar—narrated to us, from Sālim Abū al-Naḍr, from Abū Salamah ibn ʿAbd al-Raḥmān, from her. Taken together with the preceding chain, this isnād is ḥasan.

As for the third case, it is supported by the ḥadīth of Ḥamnah bint Jaḥsh, who said: “I was afflicted with severe, profuse non-menstrual bleeding, so I went to the Messenger of Allah ﷺ for a ruling and to inform him of my condition. I found him in the house of my sister Zaynab bint Jaḥsh and said, ‘O Messenger of Allah, I suffer from abundant, intense bleeding that has prevented me from praying and fasting; what do you command?’ He replied, ‘I advise you to use kirṣif (cotton), for it absorbs the blood.’ I said, ‘It is more than that.’ He said, ‘Then take a cloth.’ I said, ‘It is more than that.’ He said, ‘Then bind yourself tightly.’ I said, ‘It gushes continuously.’ He said, ‘I will direct you to two rulings; whichever of them you follow will suffice you in place of the other. If you are able to do both, then you know best.’ He then said to her:
