Did the certitude of Abu Bakr, may Allah be pleased with him, reach the level of the Prophets' certitude, peace be upon them, in terms of 'ayn al-yaqin (the eye of certainty)?

Abu Bakr As-Siddiq, may Allah be pleased with him, reached the highest levels of faith and certainty possible for those other than prophets. His faith outweighs the faith of all people on Earth. He is the best of people after the Prophets, but he does not reach their level of certainty, for Prophets are superior to saints and all other human beings, as mentioned by Shaykh al-Islam, al-Kalabadhi, and others.
