Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Bakr bin Ma’az that he says: Hazrat Rabi’ bin Khuthaym said to me: O Bakr! Guard your tongue except for that speech which is beneficial to you and not against you. For I have found people to be accused regarding their religion. Obey Allah in what you know, and what you do not know, entrust it to one who knows it. I fear for you more from deliberate actions than from actions done by mistake. Whoever among you is upon goodness today is not better, rather, they are only better than their own final evil. You do not fully follow goodness, nor do you flee from evil as is its due. You have not attained all that Allah Almighty has revealed to Hazrat Muhammad ﷺ, and all that you recite, you do not know what it is. Those hidden matters which are concealed from people are manifest to Allah. Seek a remedy for this. Then he said to himself: What is the remedy for this? It is that you repent and do not return to it again.
