Hadith Commentary: Benefits and Issues: (1)
For the sake of a Shari' (Islamic legal) benefit and necessity, it is permissible to clarify an issue in the presence of one's wife, or to have such a conversation and ask such questions to one's mother that, under normal circumstances, would be considered a cause of modesty, shyness, or embarrassment. Therefore, it cannot be said that why did Abu Musa (alayhis salam) ask this question to Aisha (radi Allahu anha), or why did that man ask this question in the presence of Aisha (radi Allahu anha), and why did the Prophet (sallallahu alayhi wa sallam) answer in this manner. That was the time of the revelation, explanation, and clarification of the Shari'ah and the religion. If modesty and shyness had been made an obstacle in asking such questions, then how would we have come to know about these issues? And how could we have informed others? And how could we have provided them with satisfaction and reassurance? (2)
There is consensus (ijma') of the entire Ummah that when a husband and wife have intercourse, even if ejaculation does not occur, performing a ritual bath (ghusl) is obligatory. In fact, the scholars are unanimous that if a person, committing an unlawful act, perpetrates a crime or sin and inserts his organ into that of an animal, a man, a child—whether alive or dead, adult or minor—whether ejaculation occurs or not, if it is with a human, then ritual bath (ghusl) is obligatory upon both. Even an innocent child, boy or girl, should be bathed. And for this, it is not a condition that the entire organ be inserted. Rather, the insertion of the glans (hasafah) is sufficient. In fact, the correct opinion is that even if one wraps a cloth and moves (in such a manner), then ritual bath (ghusl) will still be obligatory. The criminal and punishable nature of this act is a separate matter.
