To what extent is the hadith of Aisha authentic regarding the effeminate man who used to enter upon the wives of the Prophet, peace and blessings be upon him, and does this hadith refute the doubt of how he was allowed to enter their homes?

Allah Almighty has permitted women to display their adornment to men who are "non-possessors of desire," meaning those who have no need for women. These include the mentally deficient, the foolish, the idiotic, those whose desire has vanished due to old age, impotence, or illness, the eunuch, the very old man, the pre-pubescent boy, and the effeminate man (mukhannath) who has no desire.

The mukhannath, who resembles women in his manners, speech, and movements, if this is his natural disposition and not something he cultivates, then he is excused and incurs no sin, and he falls under the category of "non-possessors of desire." There was a mukhannath who used to enter upon the wives of the Prophet (peace and blessings be upon him), and they considered him among the "non-possessors of desire." However, when the Prophet (peace and blessings be upon him) heard him describe a woman, he realized that he was not among the "non-possessors of desire," so he forbade him from entering upon them.
