Allamah Mansoor Hashemi Khorasani (may Allah Almighty support him) is the preparer of the ground for the advent of Imam Mahdi and he does not make any other claim. The preparation of the ground for the advent of Imam Mahdi is not a special position for him either, but rather a righteous deed on his part, which is manifested in inviting Muslims toward Imam Mahdi and providing what is necessary for his advent, such as men and equipment, as a real and perceptible matter, and this is undoubtedly sufficient to make helping him obligatory; because Allah Almighty says: ﴿وَتَعَاوَنُوا عَلَى الْبِرِّ وَالتَّقْوَى﴾[1]; “And help one another in goodness and piety,” and preparing the ground for the advent of Imam Mahdi is the pinnacle of goodness and piety; because his advent leads to the establishment of the entire religion. Therefore, whoever becomes aware that this righteous scholar has undertaken it must help him to the best of his abilities if he believes in Allah and the Last Day, ﴿وَمَنْ عَمِلَ صَالِحًا فَلِأَنْفُسِهِمْ يَمْهَدُونَ﴾[2]; “and whoever does righteous deeds, then they prepare for themselves.”
