Riyad as-Salihin, Book 17, Hadith 1510 (In-Book)

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)‏‏)‏
