Two questions relating to Istibra for men

Salamu Alaikum all,
First of all, sorry if this is in the wrong subforum - wasn't sure..

Would really appreciate if anyone knew regarding this. Once istibra is done, and the wudhu is completed, how long does istibra's benefits last? i.e. the benefit of doing istibra is that any kind of liquid coming out of the penis becomes tahir (paak) but can this last the entire day, even if one breaks their wudhu and doesn't repeat istibra for the next wudhu because they dont need to urinate?

Second question; as said above, the benefit of it is that any liquid becomes paak - so if one did wudhu and istibra, but then afterwards got an erection and madhi (precoital fluid) came out - does this mean than the state of cleanliness is retained since this would usually break the wudhu had istibra not been done?

Sorry if this is written confusingly!
Jazakallah Khair.

a very good question u asked bro!

however by istibra maybe u mean istinja?
the rule is that istinja is necessary only when something is excreted from the privates i.e front and back...whether that maybe liquid e.g urine sperm or any other liquid or solid form e.g excretion.....whenever istinja is necessary then wudu will be nulified.

note. many ppl r not careful when doin istinja which results in drops of urine or mazi coming out later on as a result wudu will be nulified!!

Allah knows best
