الجواب وباللہ التوفیق

You have mentioned the age of your daughter as 9 years, which may be the very early age of puberty. Make sure to calculate whether the daughter was 9 years old or not at the time of her menstruation, (and these 9 years shall be calculated according to lunar calendar but not the solar calendar).

Blood before the age of nine (9) will be considered “istihadhah” and the girl will not be considered an adult yet.

Similarly, you have mentioned that the bleeding continued for only three days.

Therefore, if the bleeding started and continued intermittently and the last bleeding happened on or aftercompletion of 72 hours, then the girl will be considered an adult. But if the last blood discharge stopped even a few minutes before the completion of 72 hours, then the girl will be treated a minor.

In summary, if the girl has been determined a minor, she will remain a minor until the next three full days of blood and fasting will not be obligatory upon her.But in view of the love and importance of developing the habit of fasting and Shariah commands, she should be encouraged to fast from time to time.

In case the girl has been confirmed an adult considering the above description, then fasting has become obligatory.But if she will become sick by fasting or if her existing health condition will worsen, then she may not fast now, rather make those missed days up at a later suitable time.Please note that “fidya” (expiation) etc. will not be enough as compensation.

According to Fatawa Shami:

واوانہ بعد التسع . واقلہ ثلاثۃ ایام بلیا لیھا الثلاث المقدر بالساعات الفلکیۃ وھی اثتسان وسبعون ساعہ ... وما تراہ صغیرۃ دون تسع علی المعتمد استحاضہ۔ (الدر مع الرد ، باب الحیض:۱؍۴۷۶)

اومر یض خاف الزیادۃ لمرضہ، اوابطاء البرٔ اوفساد عضو او وجع العین اوجراحۃ اوصد اعا اوغیرہ اوصحیح خاف المرض ای  بغلبۃ الظن لا الوھد (ص۲؍۴۰۴۔ فصل فی العوارض)

فقط واللہ اعلم بالصواب
