Isḥāq ibn Manṣūr narrated to me: Abū Jaʿfar Muḥammad ibn Jahḍam al-Thaqafī informed us: Ismāʿīl ibn Jaʿfar narrated to us, from ʿUmārah ibn Ghaziyyah, from Khubayb ibn ʿAbd al-Raḥmān ibn Isāf, from Ḥafṣ ibn ʿĀṣim ibn ʿUmar ibn al-Khaṭṭāb, from his father, from his grandfather, ʿUmar ibn al-Khaṭṭāb, who said: The Messenger of Allah, peace and blessings be upon him, said: "When the muezzin says, 'Allah is the Greatest, Allah is the Greatest,' and one of you says, 'Allah is the Greatest, Allah is the Greatest'; then he says, 'I bear witness that there is no god but Allah,' and he says, 'I bear witness that there is no god but Allah'; then he says, 'I bear witness that Muḥammad is the Messenger of Allah,' and he says, 'I bear witness that Muḥammad is the Messenger of Allah'; then he says, 'Come to prayer,' and he says, 'There is no might and no power except with Allah'; then he says, 'Come to success,' and he says, 'There is no might and no power except with Allah'; then he says, 'Allah is the Greatest, Allah is the Greatest,' and he says, 'Allah is the Greatest, Allah is the Greatest'; then he says, 'There is no god but Allah,' and he says, 'There is no god but Allah'—from his heart, he will enter Paradise."
