qiyaamah

Q: According to Islam, gold and silver are real money? And will gold remain wealthy and precious always in this world before Qayamat? 

Q: When Qayamat will come, shall heaven and hell also be destroyed? Because Allah said that He will make everything vanish including the seven skies. But heaven and hell are on the 7th sky, will they also be vanished?

Q: Is there any evidence in the Hadith that it will be difficult to find guidance near the end of time?

Q: Is deleting pictures with Quraanic aayat or hadith regarded as destroying the verses and Hadith? A video went around saying that we musnt delete Hadith and Aayat as a sign of Qiyaamah is that Muslims will destroy the Quraanic verses and Ahadith themselves.

Q: As you know that a person who memorized the Quran will be told to recite on the Day of Judgment and where the person will stop, that will be his level in Jannah. My question that if a person memorized the Quran but the person's memorization is weak, will he forget on the Day of Judgment or will he remember everything?

Q: When I was 15 my friend asked me to promose to give a testify at the day of Qayamah that he was a good person. But i am scared that if I forgot to keep my promise I will be the one going to Hell, even if I didn't do anything wrong. I made the promise and now I am scared to forget about it as I will have to face Hell instead to him. Is this possible that such contract can be made for Qayamah?
