Is it obligatory to perform tayammum or wudu for a gonorrhea patient whose condition worsens with the use of water, and are fasting, prayer, and intercourse permissible with an irregular menstrual cycle due to a contraceptive drug?

Switching to tayammum (dry ablution) is permissible if harm from using water is confirmed, either through experience or by the report of a trustworthy doctor, even if the doctor is a non-believer. Tayammum is valid as long as it is the available option.

As for the blood a woman sees, it is considered menstrual blood unless its duration exceeds fifteen days; if it exceeds that, she becomes a woman experiencing istihada (non-menstrual vaginal bleeding).
