It is narrated from Hazrat Sha'bi (may Allah have mercy on him) that when a man gives his wife three divorces and she becomes pregnant, then he should perform li'an with her. Harith Akli said: O Abu Umar, does Allah Almighty not say in His Book: «وَالَّذِينَيَرْمُونَأَزْوَاجَهُمْ», so does she remain a wife after divorce? Sha'bi said: I feel shy to turn away from the truth after seeing it.
