Ikrimah narrates: In Zuhr and Asr there is no recitation except Surah al-Fatihah. At this, Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: "The Messenger of Allah (peace and blessings be upon him) commanded us (to recite), and the Messenger of Allah (peace and blessings be upon him) had conveyed the messages revealed to him from his Lord."
