Hijab from a Blind Person

Hazrat Umme Salamah (R.A) narrates that once Hazrat Maimoona (R.A) and I were in the presence of the Holy Prophet Sallallahu Alaihi Wasallam when Hazrat Abdullah Ibne Umme Maktoom (R.A) arrived. As he was blind it never occured to us that it was necessary to observe hijaab, therefore we remained seated. The Holy Prophet SallallahuAlaihi Wasallam ordered us to observe hijaab. I replied "Oh Prophet of Allah he is unable to see us." Upon hearing this the Holy Prophet Sallallahu Alaihi Wasallam said, "Are you both also blind? Are you not casting your sight upon him?" (Mishkaat, Tirmizi and Abu Dawood)

Thus, we see the Holy Prophet Sallallahu Alaihi Wasallam ordering his wives to observe hijaab even in the presence of a blind person. 

The above highlighted incidents stand as proof enough of hijaab in the era of Prophecy. How is it that as wrong doers we can throw wild accusations in the direction of the beloved Sahaabiyaat? 

May the Almighty provide us with willful understanding and keep us safe from joining the slanderers of this world. Aameen.
