Does the Prophet's saying, "If you knew what I know, you would laugh little and weep much, and you would not find pleasure in women on beds, and you would go out to the mountaintops, supplicating loudly," mean that if the Companions knew what the Prophet knew, they would be more fearful of Allah than him, knowing that the Prophet found pleasure in women and did not go out to the mountaintops, supplicating loudly?

This hadith (definition) explains that the Prophet (peace be upon him) intended to admonish the Companions and urge them to fear God. It does not contradict his enjoyment of women and his not going out to the high places (for solitary worship), because God granted him a capacity for endurance and تحمل (strength/patience) that He did not grant to others. Nor does it mean that if the Companions had known what he knew, they would have feared God more than him, for he was the one who feared God most among people and was the most pious.
