"O you who have believed, let those whom your right hands possess and those who have not [yet] reached pu- berty 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 conti- nually circulate among you - some of you, among others. Thus does God make clear to you the verses [i.e., His ordinances]; and God is Knowing and Wise."— Sahih Intl
