If someone prays facing other than the qiblah and later finds out, what should he do?

Hazrat Bara bin Azib narrates that I offered prayers facing Bayt al-Maqdis with the Holy Prophet (peace and blessings be upon him) for sixteen months. Until the verse of Surah Baqarah was revealed { وَحَیْثُ مَا کُنْتُمْ فَوَلُّوا وُجُوہَکُمْ شَطْرَہُ }. This verse was revealed after the Holy Prophet (peace and blessings be upon him) had offered his prayer. So a man passed by some Ansar who were praying, he told them the whole matter, so they turned their faces towards the Qiblah.

Hazrat Anas bin Malik (may Allah be pleased with him) narrates that the caller of the Noble Prophet (peace and blessings be upon him) came and announced that the Qiblah has been turned towards Masjid al-Haram. At that time, the Imam had already led two rak'ahs. Upon hearing this, everyone turned around and performed the remaining two rak'ahs facing the Ka'bah.

Hazrat Abdullah bin Abbas (may Allah be pleased with them) narrates that the Noble Prophet (peace and blessings be upon him) and his companions offered prayers facing Bayt al-Maqdis for sixteen months. Then the Kaaba was made the qibla.

Hazrat Ammarah bin Aws says that we used to pray facing Bayt al-Maqdis when a messenger came while our imam was in ruku and we were also in the state of ruku. He said that the Qur'an has been revealed to the Messenger of Allah (peace and blessings be upon him) and it has been commanded that you should now face the Ka'bah, so you too should turn towards the Ka'bah. Our imam, while still in ruku, turned towards the Ka'bah and all the people also turned towards the Ka'bah. Thus, we performed part of this prayer facing Bayt al-Maqdis and part of it facing the Ka'bah.

Hazrat Aqeel says that Hazrat Ibn Shahab was asked: If, on a rainy day, people pray facing a direction other than the qiblah, and during the prayer they realize that the qiblah is in another direction, what should they do? He replied that they should turn towards the qiblah, and there is no need to repeat the part of the prayer they have already performed. When the companions of the Holy Prophet (peace and blessings be upon him) were commanded to make the Ka'bah their qiblah, they did the same. Although previously they used to pray facing Bayt al-Maqdis, after this command they turned towards the Ka'bah. It was as if they performed part of the prayer facing Bayt al-Maqdis and part of it facing the Ka'bah.

Hazrat Ibn Umar (may Allah be pleased with them both) narrates that they were in the state of bowing (ruku) during the Fajr prayer, and while still in the state of bowing, they turned towards the Ka'bah.

Hazrat Mujahid says that in this verse of the Holy Qur'an { فَأَیْنَمَا تُوَلُّوا فَثَمَّ وَجْہُ اللہِ }, "Wajh Allah" means "Qiblah of Allah." Therefore, wherever you pray in the east or the west, you must face the Qiblah.

Hazrat Dhahhak bin Muzahim says that in the verse of the Holy Qur’an { وَلِکُلٍّ وِجْہَۃٌ ہُوَ مُوَلِّیہَا }, "wajhah" refers to the qiblah.

Hazrat Ibn Abbas (may Allah be pleased with both of them) says that do not keep any part of the Kaaba behind you; rather, keep it completely in front of you.

Hazrat Abu Alia says that in the verse { شَطْرَہُ } it means "in front of him."

Hazrat Aamir says that if a person, on a cloudy day, performed prayer facing a direction other than the Qibla, there is no need to repeat it.

Hazrat Hajjaj says that I asked Hazrat Ata about a person who, on cloudy days, prays facing a direction other than the Qibla. Hazrat Ata replied that his prayer will be valid. He also says that the person who asked Ibrahim and Hazrat Shabi told me that both of them also used to say that his prayer will be valid.

3417 - He said: And someone told me that he asked Ibrahim and al-Sha'bi, and they both said: It suffices him.

Hazrat Qaqa’ bin Yazid says that I and a blind man offered prayer facing a direction other than the Qiblah, so I asked Ibrahim about this, and he said that your prayer is valid.

Hazrat Mas'ar says that I asked Hazrat Ata about a person who offers prayer facing a direction other than the Qibla, so he replied that his prayer will be valid.

Ibrahim says about the person who prays facing a direction other than the Qiblah that his prayer will be valid.

Ibrahim, regarding the person who prays facing a direction other than the qiblah, says that his prayer will be valid.

Hazrat Saeed bin Musayyib says that it is not obligatory to repeat the prayer in this case.

Ibrahim says that if a man, on a rainy day, prayed facing a direction other than the qiblah, and when the clouds cleared he had already performed part of the prayer, then he should count what he has already prayed, and complete the remainder of the prayer facing the qiblah.

Hazrat Hammad, regarding the person who offers prayer facing a direction other than the Qiblah, says that his prayer is valid.
