Making Imaamat after emergence of ‘Madhi’ or ‘Wadi’

It is recorded in Binaayah, the commentary of Hidaayah that ‘Mani’ refers to the water that gushes forth and emerges with desire. It is from this liquid that one conceives a child, and it necessitates Ghusl. ‘Madhi’ refers to the water that emerges when a man engages in foreplay with his wife (or engages in lustful glances and thoughts). He is required to wash the private part and renew his Wudhu in this instance. The third category is referred to as ‘Wadi’ which emerges with the urine and after the urine. In this instance, one is required to wash the private parts and make Wudhu.

In the queried scenario, it seems that the liquid that emerged when relieving yourself could be ‘Wadi’ since it emerged with the urine, or it could be the remains of the ‘Madhi’ that was remaining in the private part. In this instance, your Imaamat was valid as Ghusl was not required. You never experienced ejaculation with force that emerged with desire which necessitated Ghusl. In conclusion, your Imaamat was valid if you made a fresh Wudhu after Istinja and then led the congregation.
