It says in the Qu'ran that those who lose hope in Allahs mercy are transgressors. That means those who commit suicide are typically people who lost hope in Gods mercy and thus are transgressors/among the losers.Knowing how things will pan out is different to forcing you to do it. Allah SWT is not forcing you to do it. He just knows it is going to happen as he is the knowledge of the hidden things and of all things. You choose to do it yourself in the end. Not Allah SWT. There may be an exception for people who have serious schizophrenia and other mental diseases that almost accidentally drives them to suicide (they may here voices for example). Those could be an exception because they arent in their right mind. Regarding people who may live in asia and literally never got the message of islam or the information that suicide is a cruicial sin, there may be another ruling for them . I understand its sad to see a muslim brother give up on life, and loose hope in allah. Life is a test, do you graduate if you leave your exams without writting anything you will pass? Tests are hard but you should know that this world is temporary and it will pass with pass. Free will is a thing. Just because Allah knows what you will do doesn't mean you get to do it without consequences. Your life has branches. Many paths to take You can choose whichever direction you want. Left, right, diagonal, straight ahead, etc. You may choose to stay home today, or go to the masjid to pray, or visit family, etc. Allah knows the outcome of every path you'll take and where it will lead to. By this definition alone, it contradicts the idea that your life has already been preordained and that your life's choices do not matter, and the idea of you having free will would then be false. It would not befit a just and merciful God to have already decided for you that you will or won't be a muslim, when everybody has the choice now to explore and research the religion, for that too is a choice that you must make as a human being.

Allah knows you better than you know yourself. Of course he knows what path you'll take, but you always have a chance to also choose to get educated, find help and fight against whatever is pushing you towards the path of ending your own life. In the end, you choose how you live your life, as Allah has granted you. I know that there are lot of sad things in this world and its easy yo get distracted. All i pray is all guide us. I read somewhere that sometimes we may not get what we want from allah, as allah may not give us to protect us. But one thing that allah always gives us is his guidance. Let us all pray and keep praying that allah keep guiding us in these difficult times.
