Entering someone's house without their permission to take one's belongings

Q: A person has possession of some of my belongings. I have brought it to his attention but he denies it completely. I am 100% sure he has it. Will it be permissible for me to enter his premises without his permission and take my belongings away and thereafter let him know that I have taken my items away. Will this entering of his premises be regarded as tresspassing in Islam and will it be infringing on his privacy?

Aayat of sajdah in Surah Naml

Q: The Sajdah in Surah Naml is normally made on completion of ayah 26 "Arsh il azeem" (as indicated in the Quraan shareef). According to fatwa hindiyya quoting Allamah Aini it says the sajdah must be made on completing ayah 25:9

وَالنَّمْلِ عِنْدَ قَوْلِهِ: {وَيَعْلَمُ مَا تُخْفُونَ وَمَا تُعْلِنُونَ} [النمل: 25]  

My question based on the above is if a person made the sajdah e tilawat in salaah after ayah 25 instead of ayah 26 will this be regarded as an extra added to the salaah thus requiring the imaam to make a sajdah e sahw or will it be counted as the sajdah e tilawat.

Water splashes while making istinjaa

Q:

1. I feel that when I am performing istanja, water gets splashed on my feet after touching my private parts. What is the ruling about these splashes?

2. Secondly I want to ask about how to clean slippers? If I am taking a bath and my body is najis, then how do I make sure that my slippers are clean after cleaning my body. I suffer from doubts about the inner side of the slippers that it becomes najis if najis water falls on my feet or slippers.

3. Last question is about washing shoes and other things which cannot be squeezed three times after pouring water on them? How do we make them paak if they happen to get najis??
