To make up for my error, I present three other notable cousin marriages.Ali was the first cousin of the Prophet, he was second uncle to Fatima Zahra.
Prophet Ibrahim AS married Sarah, his cousin.
Zayd Ibn Khattab RA elder brother of Umar and martyr married his cousin Atiqa Bint Zayd RA.
Caliph Umar RA later married Atiqa RA as well.
Do not believe when people spread dishonor on cousin marriages. Individuals far better than you and I practiced this.
