Question: In cases where the prayer should be performed in both directions due to not knowing the direction of the Qibla, if we perform the prayer only in one direction, should we perform the qadha of the prayer later?
Answer: If he is certain or almost certain or he is suspicious that the Qibla is in one of the two directions, he should pray to both directions. In the example above, if he intentionally prays only to one side, he has not fulfilled his duty and must perform Qadha for that prayer.
