Does a sick, Junub person who cannot use water need to repeat Tayammum for the next Salah?

Q: One morning, I woke up and found myself Junub (in a state of post-sexual ritual impurity) while I was sick. I could not perform Janabah Ghusl (full ritual bath to cleanse of sexual discharge). Then the time of Fajr (Dawn) Prayer became due, so I performed Tayammum (dry ablution with clean earth) intending a ritual bath. I offered the Salah with the congregation. When the time of Zhuhr (Noon) Prayer becomes due, should I perform Tayammum intending a ritual bath or intending Wudu' (ablution)? Also, is it permissible for me to stay in the Masjid (mosque) or not?

A: You have to get purified from both major and minor ritual impurities by using water. If you are unable to get purified by using water and there is no one to help you get purified by using water, you can perform Tayammum intending Taharah (ritual purification) from both major and minor ritual impurities and then offer Salah (Prayer). Also, if you have the desire to stay in the Masjid after Salah, it will be permissible for you to do so.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
