What is the ruling on delaying a prayer past its prescribed time while awaiting the result of a medical examination for a bedridden parent, or while traveling with one's mother and fearing the loss of a benefit or leaving her alone?

A distinction must be made between delaying a prayer past its prescribed time and missing congregational prayer. It is not permissible to delay a prayer past its time due to waiting for medical examinations or similar reasons, as one can pray in the waiting area or stop the car to pray. What was mentioned is not an excuse for delaying prayer unless one intends to combine it with the subsequent prayer due to hardship. As for missing congregational prayer, it is a lesser matter and is permissible when there are excuses such as hardship due to illness, fear, or caring for a patient, such as waiting at the doctor's or caring for a sick mother, as long as the prayer will be performed before its time expires.
