Yahya related to me from Malik that he had heard that Uthman ibn
Affan would sometimes never get down from the animal he was riding on
when he was doing umra, until he had returned .
Malik said,
''Umra is a sunna, and we do not know of any muslim who has ever said
that it is permissible not to do it."
Malik said, "I do not
think that anyone can do more than one umra in any one year."
Malik said that someone doing umra who had sexual intercourse with his
wife had to sacrifice an animal and do a second umra, which he had to
begin when he had finished the one that he had spoiled. He should go
into ihram at the same place where he went into ihram for the umra
which he had spoiled, except if he had entered into ihram at a place
further away than his miqat. This was because he only had to go into
ihram from his miqat.
Malik said, "Someone who entered Makka
to do umra, and does tawaf of the House and say between Safa and Marwa
while he is junub, or not in wudu, and afterwards has intercourse with
his wife, and then remembers, should do ghusl, or wudu, and then go
back and do tawaf around the House and say between Safa and Marwa and
do another umra and sacrifice an animal. A woman should do the same if
her husband has intercourse with her while she is in ihram. "
Malik said, "As for beginning umra at at-Tanim, (it is not the only
alternative). It is permissible if Allah wills for some one to leave
the Haram and go into ihram if he wishes, but the best way is for him
to go into ihram at the miqat which the Messenger of Allah, may Allah
bless him and grant him peace, used (i.e. at-Tanim), or one which is
further away."
