Always have a trained ear (teacher) to listen, you can't hear yourself nor correcr when you're a learner. Hence you need a trained ear to tell you if what you do is right or not.

While I agree with some things you mentioned, Inwould add that if one faves a language barrier or deals with someone who doesn't speak your language, simply don't talk to them as you can cause more damage then good. Also, if you don't know a topic, just say you don't know. And the best way to safeguard oneself against falsehood and doubts is: 1. Focusing more on learning Islam than learning other people's books 2. Not seeking out places that put you in that position, because at the end of the day, if something comes to you it's one thing, but if you know people aren't knowledgeable enough about Islam (from those who do 'dawah') then don't go there, also don't go to places where you know that doubts are spread. That wpuld be your own mistake and Allah says: إِنَّ الْكَافِرِينَ كَانُوا لَكُمْ عَدُوًّا مُّبِينًا Indeed, the disbelievers are ever to you a clear enemy. (4:101) And: وَلَا يَصُدَّنَّكُمُ الشَّيْطَانُ ۖ إِنَّهُ لَكُمْ عَدُوٌّ مُّبِينٌ And never let Satan avert you. Indeed, he is to you a clear enemy. (43:62) And Rasoolu Allah ﷺ said: سَيَأْتِي عَلَى النَّاسِ سَنَوَاتٌ خَدَّاعَاتٌ يُصَدَّقُ فِيهَا الْكَاذِبُ وَيُكَذَّبُ فِيهَا الصَّادِقُ وَيُؤْتَمَنُ فِيهَا الْخَائِنُ وَيُخَوَّنُ فِيهَا الأَمِينُ وَيَنْطِقُ فِيهَا الرُّوَيْبِضَةُ قِيلَ وَمَا الرُّوَيْبِضَةُ قَالَ الرَّجُلُ التَّافِهُ فِي أَمْرِ الْعَامَّةِ There will come to the people years of treachery, when the liar will be regarded as honest, and the honest man will be regarded as a liar; the traitor will be regarded as faithful, and the faithful man will be regarded as a traitor; and the Ruwaibidah will decide matters.’ It was said: ‘Who are the Ruwaibidah?’ He said: ‘Vile and base men who control the affairs of the people.’ (Sunan Ibn Majah 4036) Fools can't lead in any matter, especially not the deen.

I believe that the Qur'an shouldn't be treated like a science book to be honest. Sometimes I see people using mutashabihat to show something. One has to be really careful with this

@Mahmoud Emad i didn't say you said that, I said the Qur'an shouldn't be 'treated as a science book'. I'm nobody to tell you what you should post brother, I just mentioned my humble opinion, that's it. It wasn't a criticism of you, I said it in general.
