  Translation

143. Thus We have made you [true Muslims - real believers of Islâmic Monotheism, true followers of Prophet Muhammad SAW and his Sunnah (legal ways)], a Wasat (just) (and the best) nation, that you be witnesses over mankind and the Messenger (Muhammad SAW) be a witness over you. And We made the Qiblah (prayer direction towards Jerusalem) which you used to face, only to test those who followed the Messenger (Muhammad SAW) from those who would turn on their heels (i.e. disobey the Messenger). Indeed it was great (heavy) except for those whom Allâh guided. And Allâh would never make your faith (prayers) to be lost (i.e. your prayers offered towards Jerusalem). Truly, Allâh is full of kindness, the Most Merciful towards mankind.
