Question #544:

If the eldest son who had the obligation to offer his father’s missed prayers dies, will this obligation pass on to the eldest son’s inheritor or to the grandfather’s second eldest son (the brother of the eldest son)?

The performance of the father’s missed prayers and fasts, which were obligatory for his eldest son, will not become obligatory for the latter’s son or brother upon his death after that of his father.
