Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: “Whoever says: ‘Allah is Pure with His praises, O Allah! You are Pure with Your praises, I bear witness that You alone are the true deity, I seek Your forgiveness and turn to You.’ Whoever says these words after a gathering of remembrance, it will be a seal upon that remembrance, and whoever says them after a vain and idle gathering, it will be an expiation for that gathering.”
