Sayyiduna Anas (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever recites this after the prayer: 'Subhan Allahi al-'azimi wa bihamdihi, wa la hawla wa la quwwata illa billah' (Glory be to Allah Almighty, the Magnificent, free of every defect, and praise belongs to Him alone; nothing can happen except with the help of Allah Almighty)", the Prophet (peace and blessings be upon him) says: "when that person gets up, he has already been forgiven."
Al-Bazzar recorded it as the narration of Abu al-Zahra' from Sayyiduna Anas (may Allah be pleased with him); I do not know the narrator named Abu al-Zahra', and the rest of its narrators are thiqat (trustworthy).
