Is the wearing by all Muslim women of the proper hijab, with its conditions stipulated by scholars—and not the fashionable hijab prevalent nowadays—considered proof that they are destined for Paradise, and how would the differentiation in faith be among them?

Everyone who believes in God and performs good deeds is hoped to enter Paradise, but the Sunnis do not testify for any specific person to be in Paradise or Hellfire, except for those whom God and His Messenger have testified for. We do not guarantee Paradise for the righteous, nor do we testify for them to enter it. We seek forgiveness for the wrongdoers and fear for them, but we do not cause them to despair. As for those who do not enter Paradise initially, they will enter it if they die upon monotheism. The differentiation between them will be based on the abundance of good deeds.
