Indeed, Allah has put the truth upon the tongue and in the heart of ‘Umar

Explanation

Ibn ‘Umar (may Allah be pleased with him) reports from the Messenger of Allah (may Allah's peace and blessings be upon him) that Allah made the truth appear upon the tongue and in the heart of ‘Umar. That was a fixed and instinctive quality of ‘Umar. His son Ibn ‘Umar further says that nothing ever happened during the Prophet's lifetime and that the Companions, including ‘Umar, had their own say about it except that the Qur’an was revealed in agreement with Umar's opinion.
