It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever recites this supplication after every prayer: 'Astaghfirullah alladhi la ilaha illa huwa al-Hayy al-Qayyum wa atubu ilayh' (I seek forgiveness from Allah, besides whom there is no god, the Ever-Living, the Sustainer of all, and I turn to Him in repentance), he is forgiven, even if he has fled from the battlefield."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Ishaq except Abdullah bin al-Mukhtar, no one from Abdullah bin al-Mukhtar except Umar bin Farqad, and no one from Umar bin Farqad except Ali bin Humayd; and Ya'qub bin Ishaq is alone in narrating it."
