He was asked:

Is a soldier who plucks the white hairs from his beard committing a sin by doing so?

He replied:

Praise be to Allah, Lord of all worlds. Plucking grey hairs is disliked, whether for a soldier or anyone else, for a hadith states that the Prophet—may Allah bless him and grant him peace—“forbade plucking grey hairs and said, ‘They are the Muslim’s light.’”

He was asked:

If a man trims his nails or moustache, or combs his hair, while in a state of major ritual impurity, is there any blame upon him? Some have raised this matter, saying: “If someone in a state of major ritual impurity cuts his hair or nails, those parts of his body will be returned to him in the Hereafter. He will therefore rise on the Day of Resurrection bearing a share of major ritual impurity proportionate to what he removed, and each hair will bear a share of that impurity.” Is this so or not?

He replied:

It is authentically reported from the Prophet—may Allah bless him and grant him peace—in the hadith of Hudhayfah
