Ustadh I have done big mistake. My sister took Quran w/o my permission. She is 3. To have her return it,I gave a book with surahs and duas and said take this Quran naaudibillah. Now realize my big mistake.I have done taubah and will do all Sunnah istigfar Inn Sha Allah. But feel no hope for me.

I do not understand why you think you've done a very terrible thing; the exaggeration here is really out of place. I still don't understand what the question is.
