(22) بَابُ: {وَكَانَ عَرْشُهُ عَلَى الْمَاءِ}، {وَهُوَ رَبُّ الْعَرْشِ الْعَظِيمِ}
Narrated Anas bin Malik:
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."
