The truth is we cannot underestimate the power of making Du'a for our children. Because the Du'a of a parent on the child has an immense impact, especially as mothers. So, Insha Allah, I'd relate to certain stories from the Qur'an and Sunnah. I'll share some stories of Du'as made for children who grew up, lead and left a legacy in this Dunya.
Best way to protect your children is to keep them under the shade of your Du'a.
Just like a gardener whom when he plants a seed, he sees to make sure it grows in a good environment, getting rid of all the weeds, nurturing that seed until it grows into a beautiful flower. This becomes your condition, and even more higher when you've been blessed with that child.
