Will Our Grandchildren Say “La Ilaha Ila Allah”?

The Prophet Muhammad ﷺ warned us that “the time will come on my Ummah where the one who will be holding on his deen will be like the one who is holding on a hot burning piece of coal”. Even today it is hard for our children to hold onto faith, what about our grandchildren and generations to come? Do we think they will say “La Illaha Illa Allah”? How can we keep the flame of faith alive in our grandchildren and in future generations?
