About Abbad ibn Bishr (Radhialla Tallah Anhu)
"Ya Subhanallah (Glory be to God)! Why didn't you wake me when you were hit by the first arrow?" "I was in the midst of reciting verses of the Quran which filled my soul with awe and I did not want to cut short the recitation. The Prophet had commanded me to commit this surah to memory. Death would have been dearer to me than that the recitation of this surah should be interrupted."
