Musannaf Ibn Abi Shaybah 32341 — Reports on the description of faith

Ghalib said that Bakr said: If I were asked about the most excellent man of the mosque: "Do you bear witness that he is a believer of complete faith, free of hypocrisy?", I would not bear witness; and if I did bear witness, that testimony would be a testimony that he is in Paradise. And if I were asked about the worst or the most wicked man (the doubt is from Abu Bakr), and people said: "Do you bear witness that he is a hypocrite of complete hypocrisy, devoid of faith?", I would not bear witness, because if I did bear witness, that testimony would be that he is in Hell.
