السلام عليكم ورحمة الله أحسن الله إليكم A brother asked me if he is getting a sin if he gives his phone charger to a kafir or fasiq who he knows will sin using his phone. بارك الله فيكم وجزاكم الله خيرا

These types of questions are from tanattu (diving too deep and overthinking), which is blameworthy in Islam. The Messenger ﷺ said: "Halakal-mutannati'un," meaning, "Doomed are those who fall into diving too deep."
