ما هي المنهجية الناجعة واللينة لنصح صديق لا يصلي ويشرب الخمر ويزني، مع طلب أدعية لتيسير مهمة نصحه؟

The questioner's sister is admired for her eagerness to guide others. She is advised to stay away from the mentioned man and cut off her friendship with him, given that he is an adulterer, a wine-drinker, and neglects prayer. Her description of his morals as "good" does not align with these grave sins. She must fear Allah and beware of the footsteps of Satan. Her eagerness to invite him [to guidance] does not justify accompanying him or mixing with him. Rather, he can be invited through other means, such as sending one of her male mahrams to invite him, or sending him books and admonitory tapes.
