How can it be proven that Islam is the religion of truth, and what is the destiny of the jinn in Paradise, and will their share be like that of humans, and what is the wisdom behind the balance of good deeds, the Sirat (bridge), and intercession for the people of Paradise, knowing that I believe in the existence of Allah and His messengers?

The answer to your questions lies in three matters: beneficial knowledge, such as the Quran, to dispel doubts; righteous deeds, such as prayer and remembrance of Allah, to purify the soul; and a sincere companion who guides to good and assists in it. As for the proofs of Islam's truth and the destiny of the Jinn, these have been answered previously in earlier fatwas. Regarding the third question, the weighing of deeds on the Day of Judgment reveals the most minute particles of good and evil, establishing Allah's proof against His servants, and clarifying the manifestations of His justice and grace. It also contains other wisdoms, such as testing creation, showing the sign of happiness and misery, informing the servants of their recompense, establishing proof against them, and proclaiming that Allah is just.
