What is the ruling on participating in any of these transactions or in this business? And can one make promotional material for the company, for example website, applications, or tutorial videos about Traffic Monsoon? If there is any transaction that is impermissible, what should the Muslim who participated ignorantly do with the money he has earned through it? Please explain the reasoning behind any impermissible transaction, and if there is any way to make it compliant with Islamic law.

Assalamu ʿalaykum Shaykh. I’m considering paying a Muslim influencer who became famous through MMA to promote a halal product on Instagram. The video would be on his account, and he would speak positively about the brand. Is it permissible to partner with him for this, knowing his fame came from MMA? And if I sponsor a YouTube video with an influencer and I’m only responsible for a 90-second segment where the influencer promotes a brand in a halal way, am I sinful if the rest of the video contains music or haram content? Jazakum Allahu khayran.
