Hazrat Abu Darda (may Allah be pleased with him) said: Glad tidings are for five people! For the one who declares the purity of Allah, for the one who praises Allah, for the one who recites the word of sincerity (There is no deity except Allah), for the one who proclaims the greatness of Allah, and for the righteous boy who dies in his youth.

Hazrat Abu Al-Ahwas narrates that Hazrat Abdullah bin Masood (may Allah be pleased with him) used to declare purity in this way: "Allah is free from every defect, as many times as the number of pebbles."

Hazrat Abdullah bin Amr (may Allah be pleased with him) narrates that whoever says these words: "Allah is Pure, Great, and with His praise," then because of this statement, a tree is planted for him in Paradise.

Hazrat Shaddad bin Aws narrates that the Messenger of Allah, peace and blessings be upon him, said: The chief of supplications for forgiveness (Sayyid al-Istighfar) is that a servant should say: O Allah! You are my Lord, and I am Your servant. There is no deity except You. You created me and I am Your servant. I begin the morning upon Your promise and Your covenant as much as I am able. I seek refuge in You from the evil of what I have done. I acknowledge Your blessings upon me, and I confess my sins before You, so forgive me, for surely none forgives sins except You. Bukhari 6306. Ahmad 122

Hazrat Shaddad bin Aus narrates that the Messenger of Allah, peace and blessings be upon him, said to him: Shall I not guide you to the chief supplication for seeking forgiveness (Sayyidul Istighfar)? You should say these words: O Allah! You are my Lord. There is no deity except You. You created me and I am Your servant. And I strive to fulfill Your promise and covenant as much as I am able. I seek refuge in You from the evil of what I have done, and I acknowledge Your blessings upon me, and I confess my sins before You, so forgive me. For surely, none forgives sins except You. There is no servant who says these words during the day, and then dies before evening comes, or says them in the evening and then dies before morning comes, except that he will be among the people of Paradise.

Hazrat Hudhaifah (may Allah be pleased with him) narrates that I complained to the Messenger of Allah (peace and blessings be upon him) about the sharpness and harshness of my tongue, so the Messenger of Allah (peace and blessings be upon him) said: Then where is your seeking forgiveness? (Why do you not seek forgiveness?) Surely, I seek forgiveness from Allah one hundred times every day.

Hazrat Abu Huraira narrates that the Messenger of Allah, peace and blessings be upon him, said: Indeed, I seek repentance and forgiveness from Allah a hundred times a day.

Hazrat Ibn Umar (may Allah be pleased with them both) narrates that we used to count these words spoken by the Messenger of Allah (peace and blessings be upon him) in one gathering, and they would be one hundred times: O my Lord! Forgive me, and accept my repentance. Surely, You are the Acceptor of repentance and the Most Forgiving.

Hazrat Ibn Umar (may Allah be pleased with them) narrates that the Messenger of Allah (peace and blessings be upon him) said: "You people should repent to your Lord. Indeed, I repent a hundred times in a day."

Hazrat Abu Burdah’s father narrates that the Messenger of Allah, peace and blessings be upon him, came while we were sitting. So he, peace and blessings be upon him, said: I have never entered the morning except that I sought forgiveness in it one hundred times.
