The ruling on a person in a state of ritual impurity remaining in the mosque

Question:
The Shaykh’s position is that it is not permissible for a person in a state of ritual impurity to remain in the mosque.

Answer:
If his intention is that he is not in a state of ritual purity due to wudu', there is no harm. As for the one who has minor ritual impurity, there is a barrier to him remaining in the mosque. However, the one who has major ritual impurity, such as a menstruating woman, a woman with post-natal bleeding, or one in a state of janabah, it is not permissible for him to remain in the mosque. The Messenger (peace and blessings be upon him) said: and he ordered menstruating women to stay away from the prayer area during the Eid prayer. Therefore, it is not permissible for one with major ritual impurity to sit in the mosque. However, it is permissible for him to pass through or enter the mosque to fetch a need while walking; there is no harm in that.
