Is it required to fast consecutively when making up missed fasts?
● It is preferable to fast consecutively when making up missed fasts if they were missed due to a valid excuse.
● However, if the fasts were missed without a valid excuse, then fasting consecutively is obligatory, because making up the missed fasts in this case must be done immediately.
Separating the makeup fasts goes against the obligation of immediacy, but if someone does so, their fasts will still be valid. However, they will be sinful for delaying without a valid reason.
What is incumbent upon the one offering the sacrifice if, after slaughtering the animal, they discover that one of its internal organs is damaged or diseased?
All praise is due to Allah, and may peace and blessings be upon our Master, the Messenger of Allah.
The presence of disease or defect in the internal organs of a sheep does not affect the validity of the sacrificial animal, unless the disease leads to the animal becoming emaciated and its meat becoming corrupted.
It is stated in al-Iqnā' (2/590) by Imam al-Shirbīnī: "The third disqualifying condition: an animal with a manifest illness — meaning one whose illness visibly results in emaciation and corruption of its meat. However, if the illness is minor and does not produce such effects, it doesn`t affect the validity of the sacrificed animal." And Allah Almighty knows best.
