[Machine] I heard Junaid ibn Sab' saying, "I fought against the Messenger of Allah ﷺ as a disbeliever in the morning, and I fought with him as a Muslim in the evening." And the verse "And if it had not been for believing men and believing women" was revealed about us. He said, "We were nine people, seven men and two women."

[Machine] I fought alongside the Prophet Muhammad ﷺ as a disbeliever in the first part of the day, and I fought with him as a Muslim in the last part of the day. We were three men and nine women, and in us was revealed the verse: "And if it had not been for believing men and believing women."
