It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Your Lord, the Mighty and Majestic, said: If My servants obeyed Me, I would give them rain by night, make the sun rise upon them by day, and not make them hear the sound of thunder."

The Messenger of Allah (peace and blessings be upon him) said: "Having a good opinion of Allah is part of the best of worship."

The Messenger of Allah (peace and blessings be upon him) said: "Keep renewing your faith." It was said: O Messenger of Allah (peace and blessings be upon him), how should we renew our faith? He (peace and blessings be upon him) said: "Say 'La ilaha illallah (there is no god but Allah)' abundantly." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that a man came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah (peace and blessings be upon him), one of us commits a sin. He (peace and blessings be upon him) said: "It is written in his record of deeds." He said: Then he seeks forgiveness for it and repents. He (peace and blessings be upon him) said: "He is forgiven and his repentance is accepted." He said: Then he commits the sin again. He (peace and blessings be upon him) said: "It is written (again), and Allah Almighty does not tire (of forgiving) until you yourselves tire (of repenting)." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
