What to do with forbidden items after having repented

I have repented. But in my possession are some of the forbidden things
such as musical instruments, cassettes, films etc. Is it permissible
for me to sell them, particularly since they are worth a large amount?
Sale of such banned articles is not permissible in Islam. The Prophet
(peace be upon him) said: "When Allah forbids a thing then He forbids
its price (as well). " (i.e., its sale/purchase/trading.) [Abu Dawood,
and it is sahih] Also you know wellthat whomever you sell it to will
use it in a forbidden act; thus, it is not permissible for you tosell
it to him as Allah has prohibited this in commanding us: "laa
ta-'aawanu ala al-ithmi wal-'udwaan." (a translation of the meaning
being 'do not assist one another in sins and enmity')
And no matter how much you lose in worldly wealth, have faith that
what is in store with Allahis worthier and longer lasting. He will
compensate you with His grace, and His favor and His generosity.

Does Allah answer myprayers?

We know that Allah answers all the prayers of the believers. This can
be in 4 ways:
1- Getting what we ask for!
2- Getting something as good or better!
3- Being spared somethingbad that would have happened otherwise.
4- Being rewarded on the day of Judgment with a much greater reward
than what we were asking for on earth.

Does Allah see us?

Allah sees us and knows everything about us. He knows us better than
we know ourselves. There is not a leaf on a tree that blows away, or
stays in its place except that He knows it. There is not a dry spot,
nor a wet spot, nor a grain in the depths of the earth except that
Allah knows it.

Can we see Allah?

Allah is not like the sun. Anyone can see the sun. But Allah is the
most beautiful. Nothing is as beautiful as Allah. Actually looking at
Allah is the greatest pleasure of the people in Paradise. This
pleasure Allah does not give anyone but the believers.
