What is the ruling on sins, transgressions, and abandoning prayer for a conscious, non-delusional patient with depression (bipolar disorder) who finds it difficult to maintain religious commitment during periods of transition from illness to wellness?

The pivot of accountability (taklif) is the intellect. As long as the intellect is sound and aware of its surroundings and actions, the accountable individual is addressed by religious obligations and incurs sin for abandoning them. However, if the intellect is completely absent or no longer aware, then the pen of accountability is lifted, and the person is not held responsible for their actions.
