The ruling on deviating slightly from the direction of the qiblah in prayer

Question : The questioner asks: If it becomes clear to the one praying that he prayed facing other than the qiblah, or that he deviated slightly, does he have to repeat his prayer?

Answer : As for a slight deviation, it does not harm, and this applies to anyone other than the one in al-Masjid al-Haram, because in al-Masjid al-Haram the qiblah of the one praying is the very Ka'bah itself.
For this reason, the scholars said that if one is able to see the Ka'bah, it is obligatory to face it directly. So if you find that you are facing its direction but not the Ka'bah itself, you have to repeat the prayer because your prayer is not valid. Allah the Mighty and Majestic said: Now I am facing the Ka'bah, but if I say it is like this, the Ka'bah is on my right, and if I say it is like this, the Ka'bah is on my left, even though I am facing the direction now. This is the direction of the Ka'bah, but as long as I can see it, it is obligatory to hit it directly. As for if a person is far from the Ka'bah and cannot see it, even if he is in Makkah, it is obligatory to face the direction, and a slight deviation does not harm. For this reason, the Prophet (peace and blessings be upon him) said: Likewise, we say, for example, to those who pray facing the west, that everything between the south and the north is a margin. On the rooftops, one can see the Ka'bah.
Yes, on the upper rooftops, the marble is oriented toward the Ka'bah, there is no doubt about it. All the marble there is oriented toward the Ka'bah. But the problem here is on the second floor; the problem is in the last rows here, which might be hidden. As for what is on the rooftop, it is not hidden because the marble is facing the Ka'bah.
