Abū Umāma said he heard God’s messenger say,“Recite the Qur’ān, for on the day of resurrection it will come as an intercessor for those who recite it. Recite the two shining ones, Baqara and sūra Āl Imrān (Qur’ān, 2 and 3). for on the day of resurrection they will come as two clouds or two shades, or two flocks of birds in ranks* pleading for those who recite them. Recite sūra al-Baqara, for using it produces blessing and abandoning it produces regret, and the slothful are unable to recite it.”*The alternative may indicate that the transmitter was not sure which word was used,“clouds”or "shades”. Muslim transmitted it.
