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: "Paradise is adorned from one year to the next for the month of Ramadan, and the wide-eyed houris (hur al-'in) beautify themselves from one year to the next for the month of Ramadan. Then, when the month of Ramadan begins, Paradise says: 'O Allah, appoint for us in this month residents from among Your servants,' and the wide-eyed houris say: 'O Allah, appoint for us in this month husbands from among Your servants.'"
The Prophet (peace and blessings be upon him) said: "So whoever guards himself in the month of Ramadan, drinking no intoxicant in it, not slandering any believer in it, and committing no sin in it, Allah Almighty will marry him every night to a hundred houris, and will build for him in Paradise a palace of gold, silver, rubies and chrysolite. If the whole world were gathered and placed in that palace, it would be in it like the place where a goat is tethered in this world. And whoever drinks an intoxicant in this month, slanders a believer and commits a sin, Allah Almighty will nullify his deeds for a year. So fear (violating the sanctity of) the month of Ramadan, for it is the month of Allah. If you fall short in it, (remember that) He has given you eleven months in which you enjoy comfort and pleasure, and has kept the month of Ramadan for Himself; so beware of Ramadan."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Awza'i except Ahmad bin Abyad al-Madini, and Zuhayr bin Abbad is alone in narrating it."
