Yahya related to me from Malik that he had heard that al-Qasim
ibn Muhammad and Nafi, the mawla of Abdullah ibn Umar said, "You
cannot do itikaf unless you are fasting, because of what Allah, the
Blessed and Exalted, says in His Book, 'And eat and drink until the
white thread becomes clear to you from the black thread of dawn, then
complete the fast until night-time, and do not have intercourse with
them while you are doing itikaf in mosques,' (Sura 2 ayat 187). Allah
only mentions itikaf together with fasting."
Malik said,
"That is what we go by here."
Muwatta Malik Book 19, Hadith 4
Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim
from his father that A'isha said, "I came to Makka at the time of my
period so I did not do tawaf of the House or go between Safa and
Marwa. I complained to the Messenger of Allah, may Allah bless him and
grant him peace, and he said, 'Do what the people doing hajj do except
do not do tawaf of the House and go between Safa and Marwa until you
are pure.' "
Malik said, concerning a woman who entered ihram
for umra at the time of hajj, and she arrived in Makka during her
period and so could not do tawaf of the House, "When she fears that
the time (for hajj) is getting close, she gets into ihram for the hajj
and sacrifices an animal. She is like someone who combines the hajj
and the umra. One tawaf is enough for her. If a women starts her
period after she has already done tawaf of the House and prayed, she
does say between Safa and Marwa and stops at Arafa and Muzdalifa and
stones the jamras but she does not do the tawaf al-ifada until she is
pure and has finished her menses."
