 I remember someone speaking of one of those who was in service of the Ummah of our Prophet Sallallahu Alaihi Wasallam, and they likened him to a reed flute. A reed flute is burned on the inside, precisely because it's burned on the inside, then when you blow into it, it produces a beautiful sound. And the people who have harka, where the insides are burning, for the sake of the Ummah of our Prophet Sallallahu Alaihi Wasallam. These are people that do beautiful things out with the four people. You're making dua every single night in the wee hours at the night and throughout the day with a heart that is present and being emotionally involved in it, where you're shedding tears and in a very real way you're feeling the pain of the Ummah while you're supplicating with what is called harka. And harka is literally where your heart is burning. And we do it out of our ubodiyah, out of our servitude to Allah because that's how He wants us to be.
