They asked him how could he know that the man was eating a bread and that it was made with oil. He replied that he saw flies circling the bread, which had made him conclude that there was oil in the bread. Obviously, this is a legend. Someone who can see flies from the distance of one parasang will see a bread made with oil much sooner than he would see flies!
Or it is said that once during the time that Ibn Sina was studying at Isfahan he complained that when he gets up in the middle of the night to study, he was disturbed by the noise of the hammering of the coppersmiths of Kashan. They went and made a test. One night they told the coppersmiths of Kashan not to use their hammers. That night, said Ibn Sina, he had slept peacefully and was undisturbed in his study. Obviously this is a legend.
Many such legends have been made about Shaykh Bahi'i as well. Such things are not confined to the event of 'Ashura . However, let the people say what they would about Ibn Sina. What harm does it do? None! But in respect of individuals who are guides of mankind and whose words and deeds and whose stands and uprisings serve as a model and authority, there should not be any tahrif whatsoever in their statements, in their personality, and history.
( 21 ) How many legends have been fabricated by us Shi'is about Amir al Mu'minin 'Ali, many Peace be upon him! There is no doubt that 'Ali ( 'a ) was an extraordinary man. No one has doubts about 'Ali's courage which was superior to that of any ordinary human being. 'Ali did not encounter any contestant in battle without felling him to the ground. But does that satisfy the myth makers? Never!
For instance, there is the legend about 'Ali's encounter with Marhab in the battle of Khaybar with all the curious details about the physique of Marhab. The historians have also written that 'Ali's sword cut him into two from the middle (I don't know whether the two halves were perfectly equal!). But here they found the opportunity to weave out fables which are harmful for the faith.
It is said that God commanded Gabriel to go immediately to the earth lest 'Ali's sword when it comes down on Marhab should cut the earth into two halves, reaching right down to the Cow and the Fish. Gabriel was told to shield the blow with his wings. Gabriel went and when 'Ali struck the blow with his sword, it slashed Marhab into two halves which had they been put in a balance would have turned out to be exactly equal.
