What must a person do about the drops that emerge after urinating and nullify purification? And must he repeat the prayers he performed through Ijtihad that did not bear fruit? And how can he be certain of achieving purification? And does the organ dry merely by the urine drying on it?

Urine is impure by scholarly consensus, and prayer is not valid if it is present on one's clothes, body, or the prayer area directly connected to it. For someone afflicted with urine drops exiting after washing the penis, it is recommended to wait a little and move the penis to ensure nothing remains inside; this method varies among individuals. If urine is confirmed to exit thereafter, one must take precautions, bind the penis with a cloth or similar, then wait until the urine stops flowing, then remove the cloth, wash the penis, perform ablution, and pray. If you fear the prayer time will expire, purify yourself, take precautions, and pray. If you prayed while certain of urine drops exiting after purification and before prayer, you must repeat the prayers. However, if you doubt it after prayer, you are not required to repeat them. Drying the penis from urine is not sufficient for purification; rather, it must be washed with water. One must be cautious not to delve excessively into this matter, as it leads to obsessive thoughts.
