Working under a male senior

Q: I am a single female and have been studying something in the business field not really realising the extent of this. I started working at a company
recently and there is a male senior who I have to approach when I do not know what to do. 

  1. Should I be leaving this job?
  2. If don't end up working after the studying will it be a waste I commited?

Wazifa for labour problems

Q: Is there any dua I can pray in the shop for a worker that is troubling, comes drunk to work, if he don't want to come to work he doesn't come. I need something to pray so either he comes right or he leaves the job. I can't fire him, he has to leave on his own. Jazakallah

Income earned through leasing one's property to the bank

Q: Can you explain to me the reason why Ulamaa so severely condemn the earnings of banks? In today’s times, the majority of the wealth in banks is acquired through the deposits of people which are from halaal. Hence, if one leases out his property to a bank, the income should be halaal based on the principle that if 50% or more of one’s income is halaal and such a person has to give you a gift, you can accept it.

Will Shaitaan, Jannat and jahannum be destroyed before qiyaamah

Q:

  1. I heard in many speeches of Islamic scholars and Ulama that on the day of qiyaamah every thing will be destroyed including angels, sky and every thing except Allah. In that case will shaitaan also die on the day of qiyaamah? If so what will be his reaction, while his death is this mentioned in any authenticated hadith?
  2. I heared that Jannah is being prepared from long back to the day that the person enters in to Jannah. And allah subahanawa thaala him self makes Jannatul firdous five times a day more beautiful.  If every thing will be destroyed at the time of Qayamat what will be situation of Jannah and ​Jahannam?
