It is narrated from ‘Ubaidah (as-Salmani) regarding a menstruating woman that the bed may be the same but the blanket should be separate; if there is no blanket, then the man should put his own blanket over her.

Brief Explanation
(Commentary on Hadiths 1081 to 1086)
In this narration, it is stated that it is obligatory for a menstruating woman to stay away from a man's blanket. However, this opinion is weak and anomalous; in the authentic hadith, permission is granted to sleep together and to have intimacy, meaning merely embracing and cuddling, as will be mentioned in the following narration number (1088).
