Hazrat Thabit Banani narrates that one of the companions of Muhammad (peace and blessings be upon him) told me: Whoever says these words: "Allah is Pure and with His praise. I seek forgiveness from Allah and I repent to Him," a reward for him is written on a white tablet, then a seal of musk is placed on it. That seal is not broken until he receives the full reward of these words on the Day of Resurrection.
