I visited the Prophet (SAWA) when Ubayy ibn Ka'b was with him. The Prophet greeted me, saying, 'Welcome O Aba 'Abdillah, O the beauty of the heavens and the earths.' So Ubayy said, 'How is it possible, O Messenger of Allah, for anyone other than you to be the beauty of the heavens and the earths?' He said, ?O Ubayy I swear by Him who has rightfully sent me down as a messenger, certainly [the worth of] Husayn b. 'Ali is greater in the heavens than on the earth. And verily it is written [about him] on the right side of Allah's Throne: lamp of guidance, ark of salvation, an Imam, not weak, a [source of] dignity and pride, a landmark and a great treasure.'
