Don’t Flaunt Faults of Others
Once when Al-Kisai and Al-Yazidi were gathered before the ruler, Ar-Rashid, the time for Maghrib prayer set in, and they had to choose someone among them to lead the prayer. It wasn't a difficult choice, for Al Kisai was a well-known reciter of the Qur'an: until this very day, he is known as one of the Seven Famous Reciters. After the prayer commenced and after he finished reading the "Opening Chapter" of the Qur'an, Al-Kisai then proceeded to recite "The Disbelievers Chapter":
"Say: (0 Muhammad to these disbelievers): "0 Al- - - - .”- Kafirun '(disbelievers in Allah, in His Oneness, and in His Angels, in His Books, in His Messengers, in the Day Of Resurrection, and in Al-Qadar, etc.)!" (Qur'an 109: 1)
Although this is one of the shortest chapters of the Qur'an and one that is memorized by most young children, Al Kisai made a mistake in his recitation of it. When the prayer was over, Al-Yazidi exclaimed, exhibiting a great deal of surprise, "The Reciter and Imam of Kufa being confused about, making a mistake in, and forgetting the
'Chapter of the Disbelievers!":
When it came time to perform the 'lsha prayer later in the night, Al-Yazidi did not wait but instead put himself forward to lead the people in prayer. As soon as the prayer commenced, his voice ' began to tremble, and he forgot that Chapter of the Qur'an which is easiest to remember of all, "The Opening Chapter":
"All the praises and thanks be to Allah, the Lord (If all that exists" (Qur'an 1: 1).
