Killing snakes

Q: Does announcing for 3 days for a snake to leave your house still apply to us today or was it specifically for time when a lot of jinnaat accepted Islam and were in Madina? (In reference to the hadith from Abu Sa'ib from Abu Saeed Al Khudri (Radiyallahu Anhu) in mishkaat).

Samandar me peshaab karna

Q: Samandar ke kinaare me lowg jate he tafreeh karte he owr nahate bi he. Agar kisi ko peshaab ajae or wo us pani me peshaab karde:

1. Kiya samandar ka paani napaak hojaega?

2. Jis shaks ne peshsaab kiya he kyn ke uski majboori thi to kiya wo shaks napaak hojaega kyn ke wo peshaab uske kapron pe lagega n aaspaas ke jo log honge uske saath wo bi napaak honge kia?

Complexion of the people of Jannah

Q: Certain descriptions in terms of beauty say that the people of paradise will be white coloured/fair in complexion along with hairless, beardless, and thirty three years old. Also, the hoors are described as being white complexion as well, like pearls. First, I am not saying it is racist because that would be moronic as anyone can go to heaven, but with this, I just kind of wonder, why does a universal deity follow one beauty standard as I heard white complexion was the favoured complexion among the Arabs.
