And then it was said to her, "He is the cousin of Allah's Messenger (ﷺ) and one of the prominent Muslims." Then she said, "Allow him to enter." (When he entered) he said, "How are you?" She replied, "I am Alright if I fear (Allah)." Ibn `Abbas said, "Allah willing, you are Alright as you are the wife of Allah's Messenger (ﷺ) and he did not marry any virgin except you and proof of your innocence was revealed from the Heaven." Later on Ibn Az-Zubair entered after him and `Aisha said to him, "Ibn `Abbas came to me and praised me greatly, but I wish that I was a thing forgotten and out of sight
