"Unquestionably, the promise of Allah"—that which He promised in this world—"is truth"—regarding the promise of Paradise and the warning of the Fire—"but most of the people do not know"—meaning: the polytheists, and they are the majority of people.
Surah Yunus from verse (57) to verse (61).
﴿أَلا إِن وعد الله﴾ الَّذِي وَعَدَ فِي الدُّنْيَا ﴿حَقٌّ﴾ مِنَ الْوَعْدِ بِالْجَنَّةِ، وَالْوَعِيدِ بِالنَّارِ ﴿وَلَكِن أَكْثَرهم لَا يعلمُونَ﴾ يَعْنِي: الْمُشْرِكِينَ؛ وَهُمْ أَكْثَرُ النَّاسِ.
