A man was traveling to a town he did not know and did not pray in the direction of the qiblah; does he repeat his prayer?

The questioner : Peace be upon you. And upon you be peace. Shaykh, I have a question about prayer, Shaykh. A man, Shaykh, was traveling and arrived in a town and prayed while, Shaykh, he was one hundred percent certain that he was facing the qiblah. When he finished the prayer, Shaykh, he realized that he was not praying toward the qiblah, Shaykh. Does he repeat it?

The Shaykh : How did he pray toward the qiblah in the mosque?

The questioner : He did it in the house, Shaykh. He also prayed in the house.

The Shaykh : He started with it in the mosque.

The questioner : He was not in the mosque, Shaykh. He was traveling and he prayed in the house, meaning a house.

The Shaykh : And when traveling, he is required to pray in congregation if it does not cause him hardship.

The questioner : Yes, but he missed the congregation, Shaykh.

The Shaykh : Yes, exactly.

The questioner : Then he prayed while being certain about the direction of the qiblah, but when he finished the prayer, of course, his prayer was not toward the qiblah.

The Shaykh : He repeats it. He repeats it, yes.

The questioner : May Allah forgive you, Shaykh. Peace be upon you.
