Is Istinja’ sufficient for fluids discharged with urine?

A: It is a must to clean oneself from anything that comes out of the front and back passage (urethra and anus), except for gas, by performing Istinja' (cleansing the private parts with water after urination or defecation). Then Wudu' (ablution) must be made to offer Salah (Prayer) or any other act of worship that requires making Wudu'. As for Ghusl, it is a necessity when Maniy (sperm/vaginal secretions that are released on orgasm) is discharged lustfully; but if it is discharged (Part No. 4; Page No. 39) without lust, it is not necessary to make Ghusl.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
