• And I heard Ishaq say—again—: "If you are praying and there is a woman in front of you standing or sitting, or to your right or left, there is no harm, provided the woman is not in the middle of prayer."

He said: "And if she is at the side of a man, praying in the row with him, or following him in prayer, then her prayer is void, but the man's prayer is valid; because she is disobedient for what she was commanded—to be at the back of the rows by herself if there are no women with her; but if there are women, she should be with them in the row. Therefore, we said: she is disobedient, and the man who is at her side is obedient to Allah and His Messenger in his standing in the row with the men, and the disobedient person cannot invalidate the prayer of the obedient one."

1099 - Muhammad ibn Nasr narrated to us, he said: Hassan ibn Ibrahim narrated to us—regarding a man who was praying, and a man [had] a shaft (nushshabah) in front of him, or he had not yet set it up (rakaza), then a woman came and prayed in front of him, and the shaft was between them; does his prayer become void?—He said: Sufyan said: "If he did not remember [to set it up], his prayer is void." I said: "What if he remembered after he saw her praying in front of him; does his prayer become void?" He said: "No."
