The verses are clear. Guidance is His to give.
A short line between the signs and the hypocrites
After the signs of clouds, night and day and animals, the verse sums up. Ibn Kathir explains Allah has sent clear rulings, words of wisdom and parables, and guides people of understanding to ponder and understand them.
You have watched a dozen videos on faith and still feel unsure. It is not more information you need. The verses are already clear. What you ask for is guidance itself, and that is asked of Allah, not of the algorithm.
I need one more proof before I commit.
The signs are clear; guidance is a gift I ask Allah for.
In your next prayer, say Ihdina as-sirat al-mustaqim slowly and mean it as a request.
