Allah said:

﴿وَلِلرِّجَالِ عَلَيْهِنَّ دَرَجَةٌ﴾

(but men have a degree (of responsibility) over them.)

This Ayah indicates that men are in a more advantageous position than women physically as well as in their mannerism, status, obedience (of women to them), spending, taking care of the affairs and in general, in this life and in the Hereafter. Allah said (in another Ayah):

﴿الرِّجَالُ قَوَّامُونَ عَلَى النِّسَآءِ بِمَا فَضَّلَ اللَّهُ بَعْضَهُمْ عَلَى بَعْضٍ وَبِمَآ أَنفَقُواْ مِنْ أَمْوَلِهِمْ﴾

(Men are the protectors and maintainers of women, because Allah has made one of them to excel the other, and because they spend (to support them) from their means.) (4:34)

Allah's statement:

﴿وَاللَّهُ عَزِيزٌ حَكُيمٌ﴾

(And Allah is All-Mighty, All-Wise) means, He is Mighty in His punishment of those who disobey and defy His commands. He is Wise in what He commands, destines and legislates.

﴿الطَّلَـقُ مَرَّتَانِ فَإِمْسَاكٌ بِمَعْرُوفٍ أَوْ تَسْرِيحٌ بِإِحْسَـنٍ وَلاَ يَحِلُّ لَكُمْ أَن تَأْخُذُواْ مِمَّآ ءَاتَيْتُمُوهُنَّ شَيْئًا إِلاَّ أَن يَخَافَآ أَلاَّ يُقِيمَا حُدُودَ اللَّهِ فَإِنْ خِفْتُمْ أَلاَّ يُقِيمَا حُدُودَ اللَّهِ فَلاَ جُنَاحَ عَلَيْهِمَا فِيمَا افْتَدَتْ بِهِ تِلْكَ حُدُودُ اللَّهِ فَلاَ تَعْتَدُوهَا وَمَن يَتَعَدَّ حُدُودَ اللَّهِ فَأُوْلَـئِكَ هُمُ الظَّـلِمُونَ - فَإِن طَلَّقَهَا فَلاَ تَحِلُّ لَهُ مِن بَعْدُ حَتَّى تَنْكِحَ زَوْجًا غَيْرَهُ فَإِن طَلَّقَهَا فَلاَ جُنَاحَ عَلَيْهِمَآ أَن يَتَرَاجَعَآ إِن ظَنَّآ أَن يُقِيمَا حُدُودَ اللَّهِ وَتِلْكَ حُدُودُ اللَّهِ يُبَيِّنُهَا لِقَوْمٍ يَعْلَمُونَ ﴾

(229. The divorce is twice, after that either you retain her on reasonable terms or release her with kindness. And it is not lawful for you (men) to take back (from your wives) any of what you gave them (the Mahr, bridal-money given by the husband to his wife at the time of marriage), except when both parties fear that they would be unable to keep the limits ordained by Allah (e.g., to deal with each other on a fair basis). Then if you fear that they would not be able to keep the limits ordained by Allah, then there is no sin on either of them if she gives back (the Mahr or a part of it). These are the limits ordained by Allah, so do not transgress them. And whoever transgresses the limits ordained by Allah, then such are the wrongdoers.) (230. And if he has divorced her (the third time), then she is not lawful unto him thereafter until she has married another husband. Then, if the other husband divorces her, it is no sin on both of them that they reunite, provided they feel that they can keep the limits ordained by Allah. These are the limits of Allah, which He makes plain for the people who have knowledge.)
