Such was the mystical interpretation of the rites at Mecca taught by the Sufis to their disciples. Mecca, when Al-Ghazali made the pilgrimage, was under the rule of the Sherif Abu Hashim (A. D. 1063-1094). Half a century earlier the Karmathians, perhaps the most fanatic of all Moslem sects, had besieged Mecca, captured the city, murdered the pilgrims by thousands, and carried away the famous black stone to Bahrein on the Persian Gulf.[46] By taking away this sacred treasure they hoped to put an end to the pilgrimage, but were disappointed. In A. D. 950 the stone was returned for a heavy ransom.[47] It was because of the constant disputes between the Caliphs of Bagdad and Egypt that the defense of the holy cities was finally given into the hand of the Sherifs. Abu Hashim was a time-server, and cared more for bribes than for religion, according to the testimony of Arabian chroniclers. In A. D. 1070 he changed the name of the Fatimide Sultans for that of the Abbassides at Friday prayers, and received much bounty. In 1075 he sold the same privilege to the Fatimides, and in 1076 to the Caliphs of Bagdad. This conduct so enraged the Sultan of Bagdad that in 1091 he sent bands of Turkomans against Mecca. Chronicles of the holy city during this period show that the pilgrimage was accompanied by grave dangers because of Bedouin robbers as well as disturbances in Mecca itself. Sometimes these uprisings were directed by Abu Hashim himself, as was the case in A. D. 1094.[48] Just about the time of Al-Ghazali’s visit, the various buildings at Mecca and the _Beit Allah_ itself, had been repaired and beautified. The four _maqams_ or places of prayer for the orthodox sects as they now stand were built in A. H. 1074. The place of the Shafiʿ sect to which Al-Ghazali belonged, is directly over the well of Zem Zem, to which it serves as an upper chamber. The building, erected in 1072, is in use to-day. The great pulpit of white marble was sent to Mecca in A. H. 969 by the Sultan of Egypt. It is still in use. Perchance Al-Ghazali ascended these very stairs and addressed the pilgrims. In A. D. 1030 a violent torrent swept over Mecca, and nearly ruined the Kaʾaba. The repairs were not finished until 1040.[49] With his religious pilgrimage to Mecca and Medina it seems that Al-Ghazali’s life of strict retirement ended, except for his visit to Alexandria and beyond. Apparently he proposed to make a journey to Spain and the great Sultan of the West, Yusuf bin Tashfin, on whose behalf he had given _Fatwas_ or religious decisions, but the news of the Sultan’s death put an end to his plans, according to some authorities. Others say that at this time he was summoned to teach again at Nishapur.
