O Messenger of Allah, I left no minor or major sin without committing it." He said: "Do you not testify that there is no god but Allah and that Muhammad is the Messenger of Allah?

Anas (may Allah be pleased with him) reported:

A man came to the Prophet (may Allah’s peace and blessings be upon him) and said: "O Messenger of Allah, I left no minor or major sin without committing it." He said: "Do you not testify that there is no god but Allah and that Muhammad is the Messenger of Allah?" He repeated the question three times. He replied: 'Yes.' The Prophet (may Allah’s peace and blessings be upon him) said: "This prevails over that."

جَاءَ رَجُلٌ إِلَى النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: يَا رَسُولَ اللهِ، مَا تَرَكْتُ حَاجَّةً وَلَا دَاجَّةً إِلَّا قَدْ أَتَيْتُ، قَالَ: «أَلَيْسَ تَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللهِ؟» ثَلَاثَ مَرَّاتٍ. قَالَ: نَعَمْ، قَالَ: «فَإِنَّ ذَلِكَ يَأْتِي عَلَى ذَلِكَ».
