Imam Ibn Katheer

Allah's saying:

[وَلاَ يَضْرِبْنَ بِأَرْجُلِهِنَّ]



(And let them not stamp their feet...)
During Jahiliyyah, when women walked in the street wearing anklets and
no one could hear them, they would stamp their feet so that men could
hear their anklets ringing. Allah forbade the believing women to do
this. By the same token, if there is any other kind of adornment that
is hidden, women are forbidden to make any movements that would reveal
what is hidden, because Allah says:


[وَلاَ يَضْرِبْنَ بِأَرْجُلِهِنَّ]

(And let them not stamp their feet...)


to the end of it. From that, women are also prohibited from wearing
scent and perfume when they are going outside the home, lest men should
smell their perfume. Abu `Isa At-Tirmidhi recorded that Abu Musa, may
Allah be pleased with him, said that the Prophet said:


«كُلُّ عَيْنٍ زَانِيَةٌ، وَالْمَرْأَةُ إِذَا اسْتَعْطَرَتْ فَمَرَّتْ بِالْمَجْلِسِ فَهِيَ كَذَا وَكَذَا»



(Every eye
commits fornication and adultery, and when a woman puts on perfume and
passes through a gathering, she is such and such)
-- meaning an adulteress. He said, "And there is a similar report from
Abu Hurayrah, and this is Hasan Sahih.'' It was also recorded by Abu
Dawud and An-Nasa'i. By the same token, women are also forbidden to
walk in the middle of the street, because of what this involves of
wanton display. Abu Dawud recorded that Abu Usayd Al-Ansari said that
he heard the Messenger of Allah , as he was coming out of the Masjid
and men and women were mixing in the street, telling the women:


«اسْتَأْخِرْنَ فَإِنَّهُ لَيْسَ لَكُنَّ أَنْ تَحْقُقْنَ الطَّرِيقَ، عَلَيْكُنَّ بِحَافَّاتِ الطَّرِيقِ»



(Keep back, for you have no right to walk in the middle of the street. You should keep to the sides of the road.) The women used to cling to the walls so much that their clothes would catch on the walls.


[وَتُوبُواْ إِلَى اللَّهِ جَمِيعاً أَيُّهَ الْمُؤْمِنُونَ لَعَلَّكُمْ تُفْلِحُونَ]



(And all of you beg Allah to forgive you all, O believers, that you may be successful.) means,
practice what you are commanded in these beautiful manners and
praiseworthy characteristics, and give up the evil ways of the people
of Jahiliyyah, for the greatest success is to be found in doing what
Allah and His Messenger command and avoiding what He forbids. And Allah
is the source of strength.
