Her period stopped for six months then it came back and she has been bleeding for more than three weeks

I am suffering from irregular periods. Sometimes I have no period for
five or six months. The point here is that I got my period three weeks
ago, and uptill now it has not stopped. Please note that the colour
and smellof the blood is that of menstrual blood. What should I do?
Should I pray or not? If I have to pray, should I make up any of the
prayers I missed?.
Praise be to Allaah.
The basic principle is that the blood that comes from the woman is
menstrual blood, so long as it does not last the entire month or
onlystops for one or two days (in the month), in which case it is
istihaadah (irregular, non-menstrual bleeding). This is the correct
scholarly view, sothere is no maximum limit for the menses.
The menses may increase or decrease, and it may come earlier or later,
or it may stop for several months.
Shaykh Ibn 'Uthaymeen (may Allah have mercy on him) said: Some women
may remain without menses for four months, then get the menses for an
entire month, as if – and Allah knows best – it is withheld and then
all comes at once. And somewomen may menstruate for three or four or
five or ten days every month.

It is well known that the woman who is menstruating should notpray or
fast. As for the woman who is suffering istihaadah, she should pray
and fast, and her husband may have intercourse with her.
Based on that:
What is happening to you now is menses, so long as it does not last a
complete month or one or two days less than that, in which case it is
istihaadah; and take thisinto account for the following month.

Interesting stories about Prophet Muhammad's childhood

Abdul Muttalib (Prophet Muhammad's grandfather) was more passionate
with his grandson (young Muhammad) than with his own children. He
never left the boy a prey to loneliness, but always preferred him to
his own kids. Ibn Hisham reported: A mattress wasput in the shade of
Al-Ka'bah for Abdul Muttalib. His children used to sit around that
mattress in honour to their father, but Muhammad used to sit on it.
His uncles would take him back, but if Abdul Muttalib was present, he
would say:"Leave my grandson. I swear by Allah that this boy will hold
a significant position." He used to seat the boy on his mattress, pat
his backand was always pleased with what the boy did. Source: Ibn
Hihsam, 1/168.
It is also reported that during Amina's (Prophet Muhammad's mother)
pregnancy, she felt no pain or discomfort. She had always heard women
complaining about the hardships of pregnancy, but she felt very well.
During these months Amina had manydreams. One night in a dream she saw
a light coming out of her. The light was shining on castles of Syria.

Signs of Allah in a spider

As a man cleans his house, he might see a spider that has woven itsweb
in a corner of the house. If he realises that he ought to think about
this creature which is normally of no importance to anyone, he will
see new doors being opened for him. This tiny insect he sees before
him is a miracle of design. There is perfect symmetry in the web the
spider has woven. If, by any chance, he wonders howa tiny spider could
achieve such astonishingly perfect design, and if he makes quick
research, he will encounter some other extraordinary facts: the thread
a spider uses is thirty percent more flexible than a rubber thread of
the same thickness. The thread thespider produces is of such a
superior quality that men use it as a model for the manufacture of
bullet-proof vests.

Signs of Allah in Roses

A rose, for instance, has a strong and constant ever-changing smell.
Even with the latest technology, scientists cannot develop an exact
match of the smell of therose. Laboratory research to imitate this
smell has not yielded satisfactory results. Smells produced based on
the scent of the rose are generally heavy and disturbing. However,
theoriginal scent of the rosedoes not disturb. "It is asAllah wills,
there is no strength but in Allah" (Surat al-Kahf: 39).
