Muhammad was known among his contemporaries as Al-Amin, 'The Trustworthy', and was recognized for his integrity and honesty.

Many Muslims claim that Muhammad was known as Al-Amin, or 'The Trustworthy', before his prophetic career began. However, this assertion is based on sources written long after his death, during a time when Muslims had the power to shape narratives about their prophet. The Quran serves as a critical witness against this claim, as it documents the negative perceptions of Muhammad held by those around him. Verses in the Quran reveal that his contemporaries accused him of being a liar and a forger, suggesting that the reputation of integrity attributed to him is more myth than reality. For instance, the Quran records instances where disbelievers called Muhammad a liar (S. 6:33, 10:41) and accused him of fabricating revelations (S. 16:101, 25:4-6). These accusations indicate that rather than being universally accepted as honest, Muhammad faced significant opposition and skepticism from his own community. Furthermore, the claims of his integrity are not substantiated by any contemporary eyewitness accounts, thus raising questions about their validity. In conclusion, while Muslims may assert that Muhammad was known for his honesty and integrity, the evidence from the Quran itself contradicts this narrative. The portrayal of Muhammad by those who lived during his time suggests a far more complicated and less flattering view than the one presented by later Muslim sources.
