It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said: The Messenger of Allah (peace and blessings be upon him) said: "Whoever recites Umm al-Qur'an and 'Say: He is Allah, the One' (Surah al-Ikhlas), it is as though he has recited a third of the Qur'an."
No one narrated this hadith from Ibn Jurayj (may Allah have mercy on him) except Ali bin al-Husayn al-Ahwal (may Allah have mercy on him), and Sulayman bin Ahmad al-Wasiti (may Allah have mercy on him) is alone in narrating it.
