Asma’ bint Marthad
radiAllahu `anha

She was a Companion of the Prophet Muhamamd salAllahu `alayhi wa sallam. It is said that an ayah of Qur’an was revealed about her.

She used to take great precaution in preserving her modesty. She complained to the Prophet about male slaves coming into her room and Allah revealed,

O you who have believed, let those whom your right hands possess and those who have not [yet] reached puberty among you ask permission of you [before entering] at three times: before the dawn prayer and when you put aside your clothing [for rest] at noon and after the night prayer. [These are] three times of privacy for you. There is no blame upon you nor upon them beyond these [periods], for they continually circulate among you - some of you, among others. Thus does Allah make clear to you the verses; and Allah is Knowing and Wise. [24:58]
