Someone asked a question about Prophet Adam (AS) and whether or not he committed a sin? Well, here’s the answer. InshAllah, this will clear up many misconceptions.
Narrated AbuHurayrah: The Prophet (peace_be_upon_him) said: If any of you prays two rak'ahs before the dawn prayer, he should lie at his right side. Marwan ibn al-Hakam said to him: Is it not enough that one of us walks to the mosque until he lies at his right side? According to the version of Ubaydullah, he (AbuHurayrah) replied: No. This statement (of AbuHurayrah) reached Ibn Umar. He said: AbuHurayrah exceed limits on himself. He was asked: Do you look askance at what he says? He replied: No, but he dared and we showed cowardice. This (criticism of Ibn Umar) reached AbuHurayrah. He said: What is my sin if I remembered and they forgot?[+][Abu Dawud 002:1256]
