It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Once I was walking in Paradise when I reached a palace and stopped there. I asked, "O Jibreel! Whose palace is this?" I thought that such a palace could be mine. He replied, "This is Umar's." I walked a little further and came upon another palace, even more beautiful than the first. I asked, "Jibreel, whose is this?" Again, I thought that such a palace could be mine, but he told me, "This too is Umar's, and O Abu Hafs! In it there was also a Hoor-e-Ain. Nothing stopped me from entering it except your sense of honor." Upon hearing this, the eyes of Hazrat Umar (may Allah be pleased with him) filled with tears and he said, "I cannot express my sense of honor before you in any way."
