Anas ibne-malik (Ra) narrates that Rasúlullãh (saw) said: I passed on the night of ascension (Mai'rãj) by a people whose lips were being cut with scissors of fire. I asked Jibraíl: Who are they? He told me: They are the religious orators from amongst the people of the world, who enjoined upon others to do good but were neglectful of themselves, though they read the Book of Allãh. Were they not sensible?
