Surah Al-Baqara · سُوْرَةُ البَقَرَةِ · Juz 2
Q 2:145
وَلَئِنْ أَتَيْتَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ بِكُلِّ ءَايَةٍ مَّا تَبِعُوا۟ قِبْلَتَكَ ۚ وَمَآ أَنتَ بِتَابِعٍ قِبْلَتَهُمْ ۚ وَمَا بَعْضُهُم بِتَابِعٍ قِبْلَةَ بَعْضٍ ۚ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم مِّنۢ بَعْدِ مَا جَآءَكَ مِنَ ٱلْعِلْمِ ۙ إِنَّكَ إِذًا لَّمِنَ ٱلظَّـٰلِمِينَ
Translations
And if you brought to those who were given the Scripture every sign, they would not follow your qiblah. Nor will you be a follower of their qiblah. Nor would they be followers of one another's qiblah. So if you were to follow their desires after what has come to you of knowledge, indeed, you would then be among the wrongdoers.Certes si tu apportais toutes les preuves à ceux à qui le Livre a été donné, ils ne suivraient pas ta direction (Qibla)! Et tu ne suivras pas la leur; et entre eux, les uns ne suivent pas la direction des autres. Et si tu suivais leurs passions après ce que tu as reçu de science, tu serais, certes, du nombre des injustes.Tafsir
By God! If you provided the Jews and Christians who have been given the Scripture with every sign and proof that the change of prayer direction was the truth, they would not face your prayer direction, stubborn against what you say and too proud to follow the truth. You will not face their prayer direction after God has directed you away from it, and they will not face the prayer directions of one another, because each group calls the other disbelievers, and because they follow their desires in the matter of the prayer direction and in other sacred laws and rulings, even after the true knowledge which was revealed to you and about which there is no doubt. If you were to leave guidance, and follow their desires, you would certainly be of the wrongdoers. Here God addresses the Prophet(s) directly to show how wrong it would be to follow them. Of course, God has protected the prophet himself from ever doing so, and this as a warning for his followers after him.
