6:17 And if God touches thee with harm, none can remove it but He.
Just as in creating harm, He is one and unique, so also in repelling harm, He is unique and without equal. If all the world's folk were to gather together, the jinn and mankind holding hands to bring about a pain that is not there, they would not be able to do it; or to remove a pain that is there without God's wish, they would not find a way. Know that the wellspring of pain and remedy is one! Recognize that the source of blessing and trial is one! And see that the rising place of unbelief and faith is one! In the circle of togetherness these have one color, and in the way stations of dispersion they are multicolored. This is what that chevalier put into verse:
On your two cheeks are both unbelief and faith,
in your two lips are both pain and remedy. [DS 810]
