What is the ruling on bleeding from the vagina during the fast, when the monthly period ended ten days previously and the woman was suffering an infection in the womb. This blood is not like ordinary menstrual blood, rather it is like a short, thin thread and it happened once for a day and then stopped.


Praise be to Allaah.
 

This bleeding is not menstruation, so it does not affect the
fast, so do not stop praying because of it. But you have to do wudoo’ for
each prayer. 

Shaykh Ibn ‘Uthaymeen was asked: if a small spot of blood
comes out of a woman during the day in Ramadaan, and this (spotting)
continues throughout the month of Ramadaan and she fasts, is her fast
valid? 

He replied: 

Yes, her fast is valid, and this spotting does not matter
because it is from a vein. It was narrated that ‘Ali ibn Abi Taalib (may
Allaah be pleased with him) said: “These spots that are like a nosebleed are
not menstruation.”

The Standing Committee was asked: Sometimes my period lasts
nine days and sometimes ten. When I become pure (i.e., my period ends) and I
get up to do housework, it comes back, starting and stopping. If it comes
back after the time stated in sharee’ah that a period may last, is it
permissible for me to fast, pray and do ‘umrah? 

They replied: 

The length of the period
in your case is the length of time your period usually lasts, which is ten
or nine days. When the bleeding stops after nine or ten days, then do ghusl
and fast and pray, and do tawaaf for Hajj or ‘umrah, or a voluntary fast,
and it is permissible for your husband to have intercourse with you. Any
bleeding that resumes after the period is over because of activities that
you do or any other reason is not menstrual blood, rather it is due to some
sickness or problem, so it does not mean that you cannot pray, fast, do
tawaaf or any other acts of worship. Rather you should wash it away, like
any other impurity, then do wudoo’ for every prayer, and pray and do tawaaf
around the Ka’bah, and read Qur’aan.
