It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Some poetry is wisdom, and some eloquence is magic." And the Messenger of Allah (peace and blessings be upon him) used to recite this verse from among the poems:
[Al-Bahr al-Tawil]
"And news will be brought to you by one whom you did not provide with provisions."
