Abu Ya'qub said: "If what the pregnant woman sees is not like menstrual blood, and it does not occur at that time which used to come before that—[if] she sees it then it stops, or she sees it for days then it stops for days, [if] it is irregular for her—then the precaution for her is that she should perform the ritual bath (ghusl), then pray and fast."
681 - Ishaq said: Abu Malik informed me, from Hammad ibn Salamah, from Bakr ibn 'Abd Allah al-Muzani, who said: "My wife menstruates while she is pregnant."
682 - Muhammad ibn Yahya al-Naysaburi narrated to us, saying: 'Abd Allah ibn Nafi' narrated to us—by recitation—from Malik ibn Anas, that he asked Ibn Shihab al-Zuhri about the pregnant woman who sees blood; [he replied] that she should abandon prayer.
683 - Muhammad ibn al-Wazir narrated to us, saying: al-Walid ibn Muslim narrated to us, saying: Abu 'Amr al-Awza'i said: "The pregnant woman does not menstruate, and she does not abandon prayer; neither during her [usual] days of menstruation, nor during days other than her days of menstruation."
