(Fatwa: 406/D-116/K=1431)
Almighty Allah says in the holy Quran:
وَلَا يُبْدِينَ زِينَتَهُنَّ إِلَّا مَا ظَهَرَ مِنْهَا الآية.
And must not expose their adornment, except that which appears thereof.
Women are asked not to expose their adornment, except that which causes difficulty in concealing, as well as this order contains feet because while walking covering feet with Izar or Qamis is difficult for women, hence, according to Hanafi Fiqh, it is not necessary for women to cover their feet in salah. Yes, in the light of Hadith mentioned in Mishkat covering feet in salah is better for women.
