Is it permissible to suffice with the first ablution for performing Friday prayer, knowing that I suffer from doubt regarding the emission of drops of urine, and this is to make things easier for me and to avoid missing the Friday gathering?

If someone doubts the emission of urine drops and is not certain, their ablution and prayer are not invalidated. However, if they are certain of their emission, then it invalidates ablution and prayer, unless these drops are continuous, such that they do not cease for a time long enough to perform ablution and prayer. In this case, the person is considered to have incontinence ( سلس ), and they are not required to perform ablution for every prayer unless another impurity occurs. So, if you perform ablution for Jumu'ah prayer before its time begins, it is not prescribed for you to renew your ablution when its time enters, unless you are certain that something has occurred which invalidates it.
