Harms of self study

Q: Is this hadith sahih are that verses gone? How can this be as Allah has taken the responsibility? It was narrated that 'Aishah said: “The Verse of stoning and of breastfeeding an adult ten times was revealed1, and the paper was with me under my pillow. When the Messenger of Allah died, we were preoccupied with his death, and a tame sheep came in and ate it.”

حَدَّثَنَا أَبُو سَلَمَةَ، يَحْيَى بْنُ خَلَفٍ حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، ‏.‏ وَعَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ لَقَدْ نَزَلَتْ آيَةُ الرَّجْمِ وَرَضَاعَةُ الْكَبِيرِ عَشْرًا وَلَقَدْ كَانَ فِي صَحِيفَةٍ تَحْتَ سَرِيرِي فَلَمَّا مَاتَرَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَتَشَاغَلْنَا بِمَوْتِهِ دَخَلَ دَاجِنٌ فَأَكَلَهَا ‏.‏

Secret nikaah

Q: I am proposed to my long relation cousin. Both of our parents agreed to our marriage. Actually it is their arrangement. Also with their permission we are speaking via phone. But due to my education my parents don’t want me to do nikah right now. My question is, can I discuss only with my future wife (in shaa Allah) about mahram and give that mahram amount secretly and make this relationship to be halal? Or else am I allowed to keep one or two witnesses only and make this relationship halal? I don’t want the blame on my parents because i don’t feel like its their mistake.
