Is it permissible to create an email address with false information and send da'wah (Islamic propagation) messages to someone who does not accept advice from anyone, and is it permissible to lie about the sender's identity if he insists on knowing it?

Distance from Allah is a serious problem, and one must strive to guide people and connect them with Him. Corresponding with people through sermons and da'wah messages is beneficial. Lying is forbidden, but Islamic law permits ambiguity (ta'rid) and equivocation (tawriya), based on Umar’s statement: "Indeed, in ambiguous statements there is room to avoid lying." It is permissible to use gender-neutral pseudonyms in email. If the person insists on knowing the sender, one can use gender-neutral phrases such as: "This message is from someone who wishes you well," or "from someone who desires your happiness," and reminding them of its permissible linguistic connection. One must avoid lying, and the young man's sister should strive for his marriage and encourage him to read books of encouragement and deterrence, and stories of the Salaf and the repentant.
