Allah says in the Quran meaning o you who believe. Take your precautions and leave in groups. Or leave at once. And if you want to know whether a scholar is genuine or not. See if they adhere to Quran and Sunnah up on the understanding of the companions in their own life.
And they are not a faiq, and see when they speak, how much do they speak from their own opinions versus how much they speak directly from Quran and Sunnah and count the words. The more words they speak directly from Quran and Sunnah, the more authentic of a scholar they are likely to be in relationships. Do not make relationships with people who may harm your imaan, your health or your wealth, or with people who speak negative things.
Because this increases cortisol, which decreases testosterone, which decreases your quality of life. And do not travel with such people.
