Musannaf Ibn Abi Shaybah 37576 — The words of Rabi bin Khuthaym

It is narrated from Bakr bin Ma'iz that he said: Al-Rabi' bin Khuthaym said to me: O Bakr, keep your tongue guarded, except for what is to your benefit and not against you. For I have found people suspect regarding my religion. Obey Allah in what you know, and whatever is not within your knowledge, entrust it to the One who knows it. I fear for you what is done deliberately more than what is done by mistake. The best of you today is not truly good; rather, he is better than another who is worse than him. You do not follow good completely, and you do not flee from evil as it should be fled from. You have not attained all that Allah Almighty sent down upon Muhammad (peace and blessings be upon him), nor do you know what all that you recite is. Those secret things that are hidden from people are manifest to Allah. Seek their remedy. Then he said to himself: What is their remedy? It is that you repent and then do not return to it.
