Waki’ narrated to us, Sufyan narrated to us, from ‘Asim ibn Kulayb, from ‘Abd al-Rahman ibn al-Aswad, from ‘Alqamah, who said: Ibn Mas’ud said: "Shall I not pray for you the prayer of the Messenger of Allah, peace and blessings of Allah be upon him?" He said: "So he prayed, and he did not raise his hands except once."
