Allah The Glorious knows who will be granted Paradise. We do not know whether we ourselves will be granted Paradise or not, what about others.
We know that sinful acts are never like obeying Allah. ( ولا تستوي الحسنة ولا السيئة ( (Good deed is never like bad deed) (Sura Fossilat : 34)
Every sinful act results in its own result as every good deed results in its own reward .
Wearing Hijab is a compulsory act according to Quran , the Prophet (SAWA) and Ahlul Bayt (AS).
Obedient servants of Allah will never undermine His orders for the sake of others.
