The real standard for entry into Paradise is sound faith and righteous deeds; any individual from any era who possesses sound faith and deeds shall enter Paradise. However, after the announcement of prophethood by the Final Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, the faith of one who does not accept his prophethood is not sound, and no deed is considered righteous without sound faith.
