I would like to have a clarity on the matter of Anal sex as regards to verdicts of Ayyatullah Sistani (may almighty prolong his life), so,
a) Is it permissible or not ?? we see different view from same marja ,
two- rule 456- Islamic laws http://www.sistani.org/english/book/48/2172/
b) Is it permissible while the woman is in haydh / monthly periods? In both situation with the wife's consent.
