"O Changer of hearts! Make my heart firm on your religion."

This is such a beautiful dua.  Allah puts us in positions at times in life for us to use these duas most fervently.  

As Yasmin Mogahed says in her book Healing the Emptiness: "...the duaa that we make while 'comfortable' on the shore is not like the duaa we make while in the middle of the ocean in a storm.'

Learn this dua and use it for yourself and your loved ones.  He is the One in control of hearts and He alone can change the hearts of others to His obedience.  Call Him in broad daylight, in the depths of darkness, alone or with company and you will never be disappointed.
