question #2 Sahih al-Bukhari 7421, Book 97, Hadith 49 : How did Zainab bint Jahsh’s marriage to the Prophet Muhammad (ﷺ) differ from his other marriages?

The Verse of Al-Hijab (veiling of women) was revealed in connection with Zainab bint Jahsh. (On the
day of her marriage with him) the Prophet (ﷺ) gave a wedding banquet with bread and meat; and she used
to boast before other wives of the Prophet (ﷺ) and used to say, “Allah married me (to the Prophet (ﷺ) in the
Heavens.”
