Among the supplications of the Prophet ﷺ was, "Allah, forgive me what I have done in the past and what I will do later, what I have concealed and what I have made public, and what You know better than I do. You are the One who brings forward and the One who delays. There is no god but You."
كان من دعاء النبي ﷺ: اللهم اغفر لي ما قدمت وما أخرت، وما أسررت وما أعلنت، وما أنت أعلم به مني، إنك أنت المقدم والمؤخر، لا إله إلا أنت.
Bukhari related it in Adab al-Mufrad (673) via Khalid bin Harith, Ishaq bin Rahawayh (308) from Nadr bin Shumayl, and Ahmad (7913) from Yazid bin Harun, all of them from Abdul-Rahman Masudi, from Alqama bin Marthad, from Abu Rabi, from Abu Hurairah, who narrated it. The wording given is Bukhari's.Its chain is hasan because of Abdul-Rahman Masudi, for he was truthful, though his memory became confused before his death. However, the narrations of Khalid bin Harith and Nadr bin Shumayl from him predate that confusion. Likewise Abu Rabi, who is the Madinan, was truthful, for Abu Hatim said, "sound in hadith," and Ibn Hibban listed him among the reliable narrators. This is why Dhahabi said in Kashif, "truthful."
