Posted on: 11/07/2008 My brother in law is handicap. On his birth, his feet were upside down. With the help of German technology His feet were operated and got better. But today he still can't walk nor talk and gets seizures also. I praise him and admire his will power. May Allah bless all such children and provide them evrything in the hereafter...Ameen! |
