Narrated by Ibn 'Abbas
'Ali (Allah be pleased with him) heard that Ibn Abbas (Allah be pleased with them) gave some relaxation in connection with the contracting of temporary marriage, whereupon he

said: Don't be hasty (in your religious verdict), Ibn 'Abbas, for Allah's Messenger (may peace be upon him) on the Day of Khaibar prohibited for ever the doing of it-And eating of the flesh of domestic asses.
