What is the ruling on the presence of the groom's or bride's mother in the bridal bedroom on the wedding night, with the aim of alleviating the bride's apprehension before intercourse, and what is your advice regarding the wedding night and lawful intercourse?

If the daughter's presence with the couple leads to her observing intercourse, then this is impermissible. Scholars have explicitly stated the prohibition of engaging in intercourse in the presence of anyone, even if they are asleep. Matters of intercourse are among the secrets of married life, and it is not permissible to expose the daughter to this under the pretext of removing fear from herself, as this can be achieved through other means.
