Istibrā After the Discharge of Semen
Issue No.81- The purpose of istibrā from semen is to ensure that no more semen is left in the urethra and if after that, a moisture is discharged and one does not know whether it is semen or one of the abovementioned ṭāhir moistures, he does not have to redo ghusl. But if he has not done istibrā, and he considers it probable that the tiny particles of semen had been left in the urethra and have been discharged along with urine or another moisture, he must perform ghusl again.
