Is the ruling on سلس البول (urinary incontinence) applicable to someone from whom drops of urine emerge after urinating, and is his action of waiting until it stops, then performing istinja' (washing private parts), wudu' (ablution), and prayer valid? Is it permissible for him to perform wudu' before the time of prayer begins? Is it permissible for him to lead people in prayer, being a memorizer of the Quran, given his condition? Is it permissible to wipe over socks after his wudu' in the same manner if his wudu' is nullified? Is it permissible for him to pray with the previous wudu' if his wudu' has not been nullified when the time for another prayer begins? Is what the doctor said, that a small amount of urine does not matter and that an amount the size of a dirham does not matter, valid by analogy with istijmar (cleaning with stones)?

What you did was correct: waiting after urination for the area to dry and for the dripping of drops to cease, then performing ablution and prayer. What you feel is not urinary incontinence if the urine stops for a period sufficient for ablution and prayer. The entry of prayer time is not a condition for the validity of ablution; you may perform ablution before it. There is no impediment to you leading people in prayer if you perform ablution after the urine has stopped. Wiping over socks is permissible under certain conditions.

If you wipe over them after performing ablution for a prayer, you may wipe over them for the ablution of the next obligatory prayer. You may pray more than one obligatory prayer with a single ablution as long as your ablution is not invalidated, though it is recommended to renew ablution for the second obligatory prayer. A small amount of urine is excused.

Istijmar (cleaning with stones) is not sufficient unless the area is thoroughly cleansed of urine. The Companions were keen on perfecting istinja' (ablution/cleansing) and purifying themselves from urine.
