Hajj and other righteous deeds are means of expiation of sins, if a person does them in the manner prescribed in the Shari’ah.

It is permissible for a woman to do Hajj on behalf of her father, even if she has brothers who are grown up. Both men and women can act as deputies on behalf of others.

With regard to what is obligatory, Hajj is only required once in a lifetime. With regard to what is preferable, the more a Muslim does of Hajj, the better, even if he can do Hajj every year.

Hajj is not obligatory for a person who performs `Umrah during the months of Hajj. One who performs Hajj is not obliged to do it again.
