Tazkiyatunnafs

After praying Shubuh this morning, I red such an interseting book. The title of the book is tazkiyatunnafs. It was essences of ihya Ulumuddin, written by al ghazali. I got important cases about how to pray with Khusyu', and no praying(sholat) without khusyu'. The book informed us six cases to get khusyu. they are : Hudhurul qolb, tafahhum, ta"zhim, haibah, raja', and haya.
