Ibn 'Umar (May Allah be pleased with them) reported:
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].

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))
