In my view niqab is not obligatory as far as i know of. and i know there is difference of opinions about niqab being obligatory. And i know most of the hadith indicate that at the time of prophet Muhammad woman's face wear uncoverd and prophet did not command them to cover them.
However i found some evidence that may contradicts with the hadiths that proves niqab is not obligatory. They are
`Aisha used to say: "When (the Verse): "They should draw their veils over their necks and bosoms," was revealed, (the ladies) cut their waist sheets at the edges and covered their heads and faces with those cut pieces of cloth."
And from fath al bari
2.2 Sayyidah `Āishah (May Allah be pleased with her) said, “A woman would lower her jilbāb over her head onto her face.”
The hadith from Bukhari can be said that it is not saying that niqab is obligatory. But however the quote from fath al bari is quite clear that how a woman has to wear a jilbab and jilbab is obligatory for woman. And it shows that the face should be covered when wearing jilbab.
So my question is that this hadith and quote from fath al bari contradicts with other hadith that shows niqab is not obligatory. Or maybe i am not understanding the hadiths correctly. Can someone explain?
(also i already have seen this post)
