Zakariyya bin Yahya states: I asked Abu Ghalib about this saying of Allah Almighty (Allah Almighty says:) "Those who disbelieved will wish that they had been Muslims." Abu Ghalib said: Sayyiduna Abu Umamah (may Allah be pleased with him) narrated to me that the Prophet (peace and blessings be upon him) said: "This verse was revealed about the Khawarij: when they see that Allah Almighty has pardoned the Muslims, their rulers and their community, they will say: 'Would that we too had been Muslims.'"
Al-Tabarani recorded it. I do not know the man named Zakariyya, nor the one who narrates from him.
