Assalamualaikum, I've been using Hisnul Muslim since the beginning and I'm happy and comfortable using it. I would like to request an addition of du'a and dhikr for the Heart please because daily, people nowadays need to do tazkiyatun nafs. I used to refer to another app for these adhkar and du'as but I feel if Greentech is a much much faster app and convenient. Hope you can add this as there are many du'as for the heart that would be beneficial to the umah today.
