Combining Salahs for someone undergoing renal dialysis

A: It is permissible to combine ‘Asr and Zhuhr Prayers at the time of Zhuhr for whoever is unable to (Part No. 6; Page No. 369) offer ‘Asr Prayer on time due to the extension of the renal dialysis process until sunset, but it is impermissible to offer it or any other prayer before its due time. However, the time of Zhuhr starts post meridiem, and you can identify the time either by using the chronological table or by hearing the Adhan. Furthermore, the discharge of a small amount of blood does not nullify Wudu', but the blood itself is Najis (impure); therefore, you should wash whatever is stained of your clothes or body from it, whereas the discharge of a large amount of blood nullifies Wudu’, whether it occurs as a result of renal dialysis or for any other reason, for this is considered a discharge of a large amount of Najasah (ritual impurity) from the body.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
