“I once asked abu ‘ Abd Allah (a.s.), about the case of a woman whose husband was not present. He came and she was performing Ttikaf by the permission of her husband. Upon learning that her husband has arrived, she comes out of Masjid to her house and prepares herself until he falls on her (for sexual relation). He (the Imam) said, ’If she goes out of the Masjid before completing three days, and had not set a condition in her Ttikaf, she is required to do what is required because of Zihar (calling on oath the back of one’s wife as the back of one’s mother).”’
