وَلَئِنۡ أَتَيۡتَ ٱلَّذِينَ أُوتُواْ ٱلۡكِتَٰبَ بِكُلِّ ءَايَةٍ مَّا تَبِعُواْ قِبۡلَتَكَ ۚ وَمَآ أَنتَ بِتَابِعٍ قِبۡلَتَهُمۡ ۚ وَمَا بَعۡضُهُم بِتَابِعٍ قِبۡلَةَ بَعۡضٍ ۚ وَلَئِنِ ٱتَّبَعۡتَ أَهۡوَآءَهُم مِّن بَعۡدِ مَا جَآءَكَ مِنَ ٱلۡعِلۡمِ ۙ إِنَّكَ إِذًا لَّمِنَ ٱلظَّٰلِمِينَ
Even if thou wert to bring to the people of the Book all the Signs (together), they would not follow Thy Qibla; nor art thou going to follow their Qibla; nor indeed will they follow each other's Qibla. If thou after the knowledge hath reached thee, Wert to follow their (vain) desires,-then wert thou Indeed (clearly) in the wrong.<br/>
Yet if (wa-la-in: the laam is for oaths) you should bring to those who have been given the Scripture every sign, about your truthfulness in the matter of the direction of prayer, they will not follow your direction, out of obduracy, and you are not a follower of their direction (this is a categorical negation of his [the Prophet's] desire that they become Muslims and of their desire that he return to their direction of prayer; neither are they, the Jews and the Christians, followers of one another's direction. If you were to follow their whims, the ones to which they summon you, after the knowledge, the revelation, that has come to you, then you, if, hypothetically, you were to follow them, will surely be among the evildoers.
