Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Burdah (may Allah be pleased with him) narrates from a Companion, and in another narration it is mentioned: He says that I was sitting with an elderly Companion in the mosque of Kufa, at that time he narrated a hadith to me and said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "O people! Turn in repentance to Allah and seek forgiveness from Him. Indeed, I turn in repentance to Allah a hundred times every day and seek forgiveness from Him."
