Translation:

145. Even if thou wert to bring to the people of the Book all the signs (together) they would not follow thy Qiblah; nor art thou going to follow their Qiblah; nor indeed will they follow each other's Qiblah. If thou after the knowledge hath reached thee wert to follow their (vain) desires then wert thou indeed (clearly) in the wrong.

Notes (Tafseer)

150. See n. 147 to ii. 144 above. The Jews and Christians had a glimmering of the Qibla idea, but in their attitude of self-sufficiency they were not likely to welcome the Qibla idea as perfected in Islam. Nor is Islam, after the fuller knowledge which it has received, likely to revert to the uncertain, imperfect, and varying ideas of orientation held previously.
