The only way a woman can guarantee her passage into Paradise is if her husband is happy with her when she dies.
This idea obviously helps with the subjugation of women. It gives her a strong incentive to subordinate her wishes to her husband’s, because while she might have a chance to get into Paradise if she’s a good Muslim, the only way she can guarantee she will go to Paradise (and avoid eternal suffering in hell) is to make sure her husband is happy with her when she dies.
The basic condition for salvation for a man or woman is ‘belief’ and performance of good deeds. Obedience to husband is a various act which would further facilitate her entry to paradise. A Christian or Jewess wife just being obedient to her Muslim husband on all matters but faith in Islam do not fulfill the basic criteria laid down by Qur’an and Hadith. Only obedience to husband is not enough, because as evident form following verses and Hadith:.
“Whoever does righteous deeds, whether male or female, provided he is a believer, We shall surely grant him a new life, a life that is good, and We will certainly reward such people according to the noblest of their deeds in the hereafter.” ”[Qur’an;4:32]
“Men will be rewarded according to their deeds and women will be rewarded according to theirs”[Qur’an;4:32]
“Men are the protectors and maintainers of women because Allah has given the one more (strength) than the other and because they support them from their means. Therefore the righteous women are devoutly obedient and guard in (the husband’s) absence what Allah would have them guard…”[Qur’an;4:34]
Narrated Anas ibn Malik: Allah’s Messenger (peace be upon him) said, “When a woman observes the five times of prayer, fasts during Ramadan, preserves her chastity and obeys her husband, she may enter by any of the gates of Paradise she wishes.” AbuNu’aym transmitted it in al-Hilyah.[Al-Tirmadhi Hadth# 956]
Narrated Ubadah ibn as-Samit: The Prophet (peace be upon him) said:
“If you guarantee me six things on your part I shall guarantee you Paradise. Speak the truth when you talk, keep a promise when you make it, when you are trusted with something fulfill your trust, avoid sexual immorality, lower your eyes, and restrain your hands from injustice.” Ahmad and Bayhaqi, in Shu’ab al-Iman transmitted it. [Al-Tirmidhi Hadith#1260]
All commandments applies to applies to both men and women, unless specified, spiritually men and women are equal.
