Hadith text
Narrated `Aisha:The wives of the Prophet (ﷺ) used to go to Al-Manasi, a vast open place (near Baqi` at Medina) to answer the call of nature at night. `Umar used to say to the Prophet (ﷺ) "Let your wives be veiled," but Allah's Apostle did not do so. One night Sauda bint Zam`a the wife of the Prophet (ﷺ) went out at `Isha' time and she was a tall lady. `Umar addressed her and said, "I have recognized you, O Sauda." He said so, as he desired eagerly that the verses of Al-Hijab (the observing of veils by the Muslim women) may be revealed. So Allah revealed the verses of "Al-Hijab" (A complete body cover excluding the eyes)
Ayesha (رضی اللہ عنہا) bataati hain ke Nabi (ﷺ) ki biwiyan raat ko Al-Manasi (Madina ke qareeb khula maidan) jaati thin qaza-e-hajat ke liye. Umar Nabi se kehte: "Apni biwiyon ko parda karayein," magar Aap ne nahi kiya. Ek raat Sauda bint Zam'a (Nabi ki biwi), jo qad-aawar thin, Isha ke waqt bahar nikli. Umar ne unhe pehchaan kar kaha: "Main tumhe jaan gaya, aye Sauda." Yeh unhone isliye kaha kyunke woh chahte the ke Hijab ki ayaat nazil ho. Chunanche Allah ne Hijab ki ayaat nazil farmayi.
