I was with my fiqh teacher and we heard the athan for Maghrib. We we making our way to the masjid but we noticed that the court-yard was being cleaned. The only way around was through the bathroom. I had to go through that bathroom once and I hated it. It reeked and there were flies everywhere. I held my breath and went through. But before I knew it, we were out. The Sheik looked at me and insightfully said that was like going in and out of the dunya.
