Will hurmat-e-musaaharah become established through shaking hands with an old woman?

Q: If a person has a stomach issue, when he eats spicy or high calories foods, he gets some white drops coming out from his penis in a normal state without any errection or lust. Now if he shakes hands with an old woman without any lust or erection, will this be hurmat?

Please note that there is no lust or erection for this old lady. The person has a stomach heat problem because of which he gets these drops when he eats spicy food.

Drug addict leading taraweeh salaah

Q: I want to know something about drugs. I will be leading taraweeh for the first time this year. Unfortunately, I am in the grasp of drugs. Is it true that if I take them within 40 days of Ramadhaan, the taraweeh I lead will not count?

Also, does this apply to drugs other than marijuana, like molly, cocaine, and lsd?

Please take into account that I am trying to stop, but slowly as the withdrawal effect is immensely strong.

Paying zakaat on one's contribution towards a provident fund

Q: At my previous job, some years back there was a provident fund which I contributed a certain percentage and the company contributed a certain percentage. However after I left that job I forgot about that money and now while trying to take it out from the fund, I am experiencing difficulties as many years passed by and the account became redundant. Do I have to pay zakaat on that amount.
