Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن ابن عمر رضي الله عنهما قال: ما سمعت عمر رضي الله عنه يقول لشيء قط: إني لأظنه كذا إلا كان كما يظن. ((رواه البخاري))
I never heard 'Umar (May Allah be pleased with him) relating anything that he conceived it to be so-and-so, but that it proved to be as he had conceived it."[Al-Bukhari].
