This is Mishary Rashid's nasheed, "Ana Al-'Abd" meaning "I am the Slave". The lyrics are taken from the original poem of the same name by Ibn 'Abdil Qawiyy. I'm not a huge fan of nasheeds but this one is extremely beautiful and more importantly contains a very important and beneficial theme for all of us inshaAllah.
