The waters that acknowledged ’Alí to be the Prophet’s successor became “sweet” or fresh on the eighteenth of Zú-’l-hijjah. The rest either remained salt or turned brackish. The birds that accepted ’Alí as Muhammad’s heir were taught to sing like a nightingale or to talk like a parrot. Those that denied him were stricken deaf and dumb. For the angels who delighted to honour him a sumptuous palace was built with slabs of gold and silver in alternate order. Two hundred thousand domes crowned this edifice, and half of them were made of red rubies, and half of green emeralds. Through the courtyard flowed four rivers: one with water, one with milk, another with honey, and a fourth with wine. Trees of gold, bearing fruits of turquoise, grew along the banks, and on the branches were perched the most marvellous birds. Their bodies were made of pearls, their right wings of rubies, and their left wings of turquoises. All the hosts of heaven gathered together, praising God. The birds dived, singing, into the streams. The angels clapped their hands and shouted. The houris joined in the chorus. Then, with one accord, they all raised their voices in homage of ’Alí and his wife, the Prophet’s daughter, Fatima. Lovers should remember to strengthen the bond of affection by exchanging rings. The men should kiss each other frequently whenever and wherever they meet. The servants should kiss their master’s hands, and the children those of their parents. If a Muslim smile on his brother-Muslim on this holy a’yád, God will smile on him on the day of the resurrection. If he die, he will receive the rewards of a martyr of the faith. If he call on a true believer, he will be visited in the grave when he draws his last breath by seventy thousand angels. If he neglect neither the ordained prayer nor the prescribed purification, he will be entitled to rank with the man to whom God has granted the rewards of one hundred thousand pilgrimages to Mecca. And a week later, on the 25th of Zú-’l-hijjah, the angel of revelations brought down from heaven to the Prophet the chapter of the Kurán, entitled Man, and told Muhammad that God congratulated him on the virtues of his family. VIII.--PERSIAN SÚFÍISM; AND PERSIAN SHIAHISM IN ITS RELATION TO THE PERSIAN PASSION-DRAMA. Since the narrative which follows this introduction is written rather from the Persian and Shiah than from the Turkish and Sunni point of view, it is necessary for us to dwell briefly on two more important subjects in connection with Persian thought:--(_a_) on the love of metaphysical speculation which vindicates the claim of Aryan thought to be free, and which has given rise to the doctrines of Súfíism,--our immediate consideration; and (_b_) on the growth of Shiahism, the State religion, and more particularly in its relation to the Passion-Drama, which is the outcome of the Muharram celebrations in honour of Huseyn’s martyrdom.
