Chapter 12 | Repentance, Seeking Forgiveness, Regret, and Admission (of Guilt)
حماد بن عيسى عن إبراهيم بن عمر عن أبي عبد الله عليه السلام: قال من قال ثلاثا: سبحان ربى العظيم وبحمده استغفر الله ربى وأتوب إليه، قرعت العرش كما تقرع السلسلة الطشت.
18.Ḥammād ibn ʿĪsā narrated from Ibrāhīm ibn ʿUmar, from Abū ʿAbdillāh who said, “Whoever says three times, ‘Glory be to my Lord, the Great, and praise be to Him. I seek forgiveness from my Lord and turn penitently to Him,’ the Throne [of Allah] makes a sound like the sound of chains striking a bowl.”
