The Duty of One Who Becomes Ṭāhir at the End of Time
Issue No.454- If a ḥā’iḍ woman becomes ṭāhir when the time for prayers is nearing its end, and finds that she does not have enough time for ghusl, but she has time to perform tayammum and offer one rak‘at of prayer within the prescribed time and the rest out of the time, then it is not obligatory for her to offer that prayer. However, if regardless of the shortage of time, it is incumbent upon her to perform tayammum due to other reasons, like when water is harmful to her, she should perform tayammum and offer that prayer.
