Fadl ibn Shazaan (Died 260 A.H) may Allah (swt) have mercy on him was the companion of the eighth Holy Imam Al-Reza(a.s), who confirms the attack on the house of Sayeda Fatima(s.a).
Fadl ibn Shazaan:
And Abu Bakr said in his illness as a result of which he died,
"I wish I had not attacked the house of Fatima (s.a.), even though it was closed for fight"
. "He regretted" so his repentance is not except due to a sin.
