It is narrated from Abu Raja' al-Utaridi that Ibn Abbas (may Allah be pleased with him) led us in the morning prayer while he was the governor of Basrah. He recited the qunut before the bowing (ruku') and raised his hands so high that if a man had been in front of him, he would have seen the whiteness of his armpits. When he had completed the prayer, he turned his face towards us and said: This is the prayer about which Allah Almighty has said in His Book: "Guard the prayers, especially the middle prayer, and stand before Allah in devout obedience." [Surah al-Baqarah: 238]
