HADITH OF THE DAY
TO OBSERVE VEILS
Narrated by Umar
I said, "O Allah's Messenger (Peace & Blessings of Allah upon Him)! Good and bad persons enter upon you, so I suggest that you order the mothers of the Believers (i.e. your wives) to observe veils."
Then Allah revealed the Verses of Al-Hijab.
[Vol-6 Hadith-313 Sahih Al-Bukhari]
