Al-`Awfi reported that Ibn `Abbas said:

وَلِكُلٍّ وِجْهَةٌ هُوَ مُوَلِّيهَا

(For every nation there is a direction to which they face (in their prayers))

"This talks about followers of the various religions. Hence, every nation and tribe has its own Qiblah that they choose, while Allah's appointed Qiblah is what the believers face."

Abul-`Aliyah said, "The Jew has a direction to which he faces (in the prayer). The Christian has a direction to which he faces. Allah has guided you, O (Muslim) Ummah, to a Qiblah which is the true Qiblah." This statement was also related to Mujahid, `Ata' Ad-Dahhak, Ar-Rabi` bin Anas, As-Suddi, and others.

This last Ayah is similar to what Allah said:

لِكُلٍّ جَعَلْنَا مِنكُمْ شِرْعَةً وَمِنْهَـجاً وَلَوْ شَآءَ اللَّهُ لَجَعَلَكُمْ أُمَّةً وَحِدَةً وَلَـكِن لِّيَبْلُوَكُمْ فِى مَآ ءَاتَـكُم فَاسْتَبِقُوا الخَيْرَاتِ إِلَى الله مَرْجِعُكُمْ جَمِيعاً

(To each among you, We have prescribed a law and a clear way. If Allah had willed, He would have made you one nation, but that (He) may test you in what He has given you; so compete in good deeds. The return of you (all) is to Allah.) (5:48)

In the Ayah (2:148), Allah said:

أَيْنَ مَا تَكُونُواْ يَأْتِ بِكُمُ اللَّهُ جَمِيعًا إِنَّ اللَّهَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ

(Wheresoever you may be, Allah will bring you together (on the Day of Resurrection). Truly, Allah is able to do all things.) meaning: He is able to gather you from the earth even if your bodies and flesh disintegrated and scattered.
