<b>Guidance from the Hadith:</b><br> 1) It is permissible to backbite corrupt transgressing people in order to warn others from them.<br> 2) It is permissible to display an attitude towards someone contrary to what one feels in his heart for him if there is an interest in doing so.<br> <br> <b>Benefit:</b><br> The man mentioned in the Hadith is ‘Uyaynah ibn Hisn, who was not a Muslim back then, although he pretended to be a Muslim. Therefore, the Prophet (may Allah’s peace and blessings be upon him) wanted to reveal his reality to the people in order for them not to be deceived by him. There are many situations that happened during the life of the Prophet (may Allah’s peace and blessings be upon him) and after his demise that indicate the weak faith of that man. Then, he committed apostasy with those who did so and was brought as a prisoner to Abu Bakr (may Allah be pleased with him). Hence, the Prophet’s description of him as an evil brother of his people is a clear sign of his prophethood.
