+ Positive Mitzvah
The deceased brother’s childless widow to remove the shoe (Chalitza) of her husband’s brother.
“If the man does not wish to marry his deceased brother’s childless widow…” As it says in Devarim 25: 7 “she shall remove the shoe from on his foot…” 5:9
The performance of removal of the (Chalitza) shoe should only be done under the supervision of Rabbis who are expert and knowledgeable in these matters.
Whoever does not allow the removal of the shoe by his brother’s childless widow transgresses this positive commandment.
There are men who refuse to have the shoe removed by the brother’s childless widow because they say this is dangerous to do so.
They are greatly mistaken as the ways of God are correct and no harm will befall them if they do this Mitzvah.
On the contrary if they will not perform this positive Mitzvah they sin greatly.
This is applicable in all places and at all times.
