Even if there were not, concerning him, clear and evident signs, yet the sight of him would have told you the news.

`Abd Allah ibn Rawaha al-Ansari -- the great-grandson of the poet Imru' al-Qays -- said of the Prophet:

law lam takun fihi ayatun mubina
lakana manzaruhu yunabbi'uka bi al-khabari

Even if there were not, concerning him, clear and evident signs, yet the sight of him would have told you the news.

Ibn Hajar narrated it in al-Isaba (2:299) and said: "This is the most beautiful verse of poetry by which the Prophet şallAllāhu álayhi wa sallam was ever praised."
