Saiyed Imam-ud-din alias Syed Imam Shah, whose brief history is recorded here. Syed Imam-ud-din was the youngest of the eighteen children of Pir Syed Hasan Kabir-ud-din bin Pir Syed Sadruddin who was a descendant of Hazrat Imam Ja'far as-Sadiq. He was born on Thursday, the 21st Moharrum, 834 A.H.(1430 C.E/1486 Savant) at Uchh Sharif near Multan. His mother, Hurmat Khatun, was a daughter of Syed Alauddin bin Syed Kamal-ud-din. His other appellations are Syed Abdur-Rahim, Indra Imamdeen, Syed Imam Shah, etc... but he is famous as Syed Imam-ud-din or Syed Imam Shah amongst the Ismailis and as Pir Imam Shah or Pir Indra Imamdeen amongst the Imamshahis. He was about 19 when his father, Pir Hasan Kabirud-din breathed his last. All the progeny of Pir Hasan Kabir-ud-din are said to have been present at the time of his death, except Syed Imam-ud-din who is reported to have been away on a preaching mission. In his absence, his eighteen brothers hurriedly divided whatever property their father had left behind, depriving Syed Imam-ud-din of his share of the inheritance. Incidentally Syed Imam-ud-din all of a sudden returned to Uchh Sharif on the day his father was to be buried and to his great grief learnt of his father's demise. On the way to the graveyard, he learnt to his great chagrin of his brothers' treachery. He immediately halted the funeral procession and addressing his father's coffin demanded his inheritance. His brothers and their minions laughed at this apparent foolishness, but Syed Imam-ud-din was adamant. For more than three hours he held up the funeral procession and went on imploring his father for his due share. At last, it is said that, a hand appeared from the coffin with a rosary (Tasbih) which he is said to have respectfully received but kept on imploring for more. Then the hand appeared a second time with a lump of sugar (missary), which he immediately put into his mouth and expressed his satisfaction as having received his share of the inheritance. He then allowed the procession to proceed. Some of the ignorant and sycophantic people started misleading him that this miracle signified his succession to his father as Pir. Syed Imam-ud-din though tender of age about 19 but highly learned in theology and mysticism, understood the real purpose of these posthumous bequests from his father. He knew well that the office of Pir (piratan) can only be bestowed by the Imam of the time (Imam-e-Zaman) and that even a spiritually accomplished and popularly acknowledged Pir like his widely revered father did not enjoy any power or right to bestow such a gift. He immediately nipped the mischievous rumors in the bud and categorically, declared to all present that it was the prerogative of the Imam of the time (Imam-e-Zaman) alone as was evident by the cases of his father and grandfather. He explained the significance of the posthumous gifts from his father in the way that the rosary (Tasbih) signified the behest of his father to him to be more and more devoted to prayers and the lump of sugar (Missary) signified his father's urging to carry on the missionary work by sweet persuasion (preaching). After his father's passing away, Syed Imam-ud-din remained at Uchh Sharif when he received the summons from Hazrat Imam Muhammad bin Islam Shah whose headquarters at that time were at Kehk in Iran.
