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.

Reciting behind the Imaam

Q: When praying behind the imam in Zuhr and Asr prayer, should we recite Surah Fatiha and a Surah in the first 2 rakaats and only Surah Fatiha in the last rakaat.

In Fajr, Maghrib and Esha, I know we should keep quiet and listen but in the last 2 rakaats when the imam is silent, should we recite Surah Fatiha only?

Wearing one shoe and walking

Q: What is the explanation of this hadith:

Sayyiduna Abu Hurayrah (radiyallahu ‘anhu) reports that Nabi (sallallahu ‘alayhi wa sallam) said, “None of you should walk in one shoe. Remove both or wear both”

(Sahih Bukhari, Hadith: 5856 and Sahih Muslim, Hadith: 2097).

Missing salaah due to college

Q: My parents are forcing me to miss Salah for Education. Is it correct! I am admitted to a college where I am not allowed to pray salah. I am missing Asr and Maghrib Salah every day. On complaining this to my parents they are not listening to me and forcing me to go to the same college. I am not allowed to pray at my college or go out of the college. Every day I am praying Asr and Maghrib Salah at night after Isha Salah as Qaza Salah.

Is it correct that I miss Salah for Education? Should I obey my parents? They are blackmailing me emotionally. Should I change my college?
