In Al-Zuhd al-Nabi it has been narrated that Imam Baqir (a.s) quoted on the authority of God's Prophet (a.s) that God the Almighty said
“I am better aware of what will improve My religion. There are those religious believers who strive to worship Me, and get up from their warm cuddly beds for nighttime supplications. They impose hardships on themselves for My worship. Since I love them, I make them fall asleep to protect their health. They go to sleep and wake up in the morning, and blame themselves. However, they do not know that if I had left them to themselves to worship Me as much as they wanted, they would get haughty and become ruined. This will be due to their conceit to the extent that they think they are better than all others who worship Me, and they have passed all the stages of worshipping, and have perfected it. This will force them away from Me, while they themselves think that they are close to Me. Thus those who do good deeds should not rely on deeds which they do for getting rewards from Me, since if they try, they will trouble themselves and waste their time spending it in My worship. Still they will be deficient, and cannot attain the depth of My Servitude. They cannot attain any of the honor, Heavenly blessings, divine attention and high ranks near Me that they seek. They can only rely on My Mercy, and be pleased with My Favor, and they should have a good opinion about Me and trust. Then they will benefit from My Mercy, and by My forgiving I will take them to Heaven, and Forgive them since I am God the Beneficent and the Merciful and am known by these Names.”
