What are the sources of the story on the murder of Rabbi Yehuda Halevi in the Wailing Wall?

Very vague! "Legend claims that he was killed within sight of Jerusalem, although recent studies suggest that he died en route, in Egypt." http://www.bookrags.com/research/yehudah-ha-levi-eorl-14/ "Legend has it that he was killed in 1141 by an Arab horseman as he kissed the soil of the Temple Mount in Jerusalem, but there is no historic confirmation of this, since he cannot be traced beyond Egypt on his way to Palestine." http://www.bookrags.com/research/halevi-yehuda-c-10751141-eoph/ "Contrary to a prevalent theory, his poetry shows beyond doubt that his pilgrimage was a completely individual act and that he had no intention of setting off a mass pilgrimageirst. Halevi sailed for Alexandria. Arriving on September 8, 1140, he was enthusiastically greeted by friends and admirers. He then went to Cairo, where he visited several dignitaries, including the Nagid of Egypt, Samuel ben Hanania, and his friend Halfon ben Nethaniel Halevi. He did not permit himself to be persuaded to remain in Egypt, but returned to Alexandria and sailed for Palestine on May 14, 1141. He died during the summer, presumably after having reached Palestine." http://www.bookrags.com/wiki/Yehuda_Halevi "According to legend, he was kneeling at the Wailing Wall when a galloping Arab horseman rode him down and crushed him to death." http://www.bookrags.com/biography/judah-halevi/ Nov 22 08, 7:11 AM
