Putting Flowers on the Graves – Sheikh Assim Al Hakeem

If a woman is having her monthly menstruation, can she give ghusl & shroud her dead mother, sister, grandmother, specially if others are present. People say that women at the time of menstruating are impure, so shouldn’t touch the dead body during ghusl or during or after shrouding, and shouldn’t be present or near the deceased or touch them for that matter, is it correct?
