And in this wise We have made you a community justly balanced, that ye may be witness against the man kind and that the apostle may be in regard to you a witness. And We appointed not the Qiblah which thou hast had save in order that We might know him who followeth the apostle from him who turnoth back upon his heels. And of a surety the change is grievous save unto those whom Allah hath guided. And Allah is not one to let your faith go wasted; verily Allah is unto mankind Tender, Merciful.
