Divine Knowledge

What is the evidence for the concept of Ilm-e-Ladduni of our Prophet Muhammad SAWA and the 12 Imams? Zoheir Ali Esmail	I understand from al-Kafi that the throne or 'Arsh of God is His knowledge that encompasses all things. Ayat al-Kursi says that the Kursi encompasses all things. What is the Kursi of God and how is it different from the 'Arsh? Sayyed Mohammad Al-Musawi
In Surah Rum, why did the verse say that the Byzantines will overcome in three to nine years, according to the Saheeh International translation, instead of giving the exact number of years since Allah SWT has the knowledge of the unseen? Sayyed Mohammad Al-Musawi	If the polytheists and infidels will be in hell then would that not cover the vast majority of people since the time of Adam (a)? If yes, then why was such a world created by a Creator whose love is limitless and who knows the destiny of each human? Sayyed Mohammad Al-Musawi
