H 111 - Informed us a group of scholars from Abu Abdullah Husain from Ali bin Sufyan Bazufari from Ali bin Sinan Musali Adal from Ali bin Husain from Ahmad bin Muhammad bin Khalil from Ja’far bin Ahmad Misri from his uncle, Hasan bin Ali from his father Abu Abdullah Ja’far bin Muhammad from his father, Imam Muhammad Baqir عليه السلام from his father, the owner of corns , Chief of worshippers, from his father, Husain, the Pure and the martyr from his father. Amirul Momineen عليه السلام that he said: The Messenger of Allah صلى الله عليه وعلى آله وسلم said on the eve of his departure from the world: “O Abul Hasan, bring a scroll and pen and ink.” Then he dictated his will, till he came to the words: “O Ali, very soon after me there will be twelve Imams and after them there would be twelve Mahdis. And you are the first of the twelve Imams. The Almighty Allah has named you as Ali Murtadha, chief of believers, the great truthful one (who testified to the Prophet), the great discriminator (and through you truth would be distinguished from falsehood) and named you as Mamun and Mahdi, these names are not appropriate for anyone else other than you.” “O Ali, you are my successor and in charge of my Ahle Bayt عليه السلام, whether I am alive or dead. In the same way, you will be my successor on my wives, thus ones you leave in my marriage contract would meet me tomorrow on Judgment Day and I am aloof from one you divorce; and on Judgment Day neither would she see me nor would I see her. After me you are the successor and Caliph on my Ummah. When your death approaches, you will transfer my successorship and legateeship to my son, Hasan, the righteous and rightful. When his death comes, he would entrust it to my son, Husain, the pure and the martyr and when his death comes, he would hand it over to the chief of the worshippers and the owner of corns (Ali) and when his end comes, he would transfer it to his son, Muhammad Baqir and when his last moments approach, he would entrust it to his son, Ja’far Sadiq and when his death comes, he would leave it to his son, Musa Kadhim and when his death comes, he would leave it to his son, Ali (Ridha) and when his end comes, he would give it to his son, Muhammad, the trustworthy (Taqi) and when his death arrives, he would present it to his son, Ali (Nasih). And when his death comes, he would transfer it to his son, Hasan (Fazil) and when his death arrives, he would leave it to his son (Muhammad), who is the protector of the Shariah of Muhammad. These were the twelve Imams and after them there will be twelve Mahdis. When the last moments of the twelfth Imam will approach, he will hand it over to his son, who is the foremost proximate; and he has three names: My name, name of my father: Abdullah and Ahmad; and third will be Mahdi and he will be the first of the believers.”
