Imam Jafar Sadiq (a.s.) says: ‘Our Qaim will reappear alone. When he will enter Masjidul Haram, he will be in a state of solitude. He will spend the night in the same solitary state. When the darkness will descend on the horizon, Jibraeel, Mikaeel and the angels will descend in hordes and Jibraeel will address Imam thus – O our master, your command will be obeyed. Your orders shall be executed.’ sSubsequently, Imam (a.t.f.s.) will touch his face and say:
الْحَمْدُ لِلَّهِ الَّذِي صَدَقَنَا وَعْدَهُ وَأَوْرَثَنَا الْأَرْضَ نَتَبَوَّأُ مِنَ الْجَنَّةِ حَيْثُ نَشَاء فَنِعْمَ أَجْرُ الْعَامِلِينَ
All praise belongs to Allah who fulfilled His promise to us and made us to inherit the earth. We will stay in heaven where we fancy. This is the best reward for the good doers.( sure zumar : 74)
Then he will stand between Rukne Yamani and Maqame Ibrahim and with his soothing voice he will address his friends scattered in the various nooks and corners of the world. O our chosen ones, our confidantes, our companions and those who are selected by Allah for my assistance and were gathered on the earth prior to my reappearance, wherever you all are, rush towards me at once!” Imam Jafar Sadiq (a.s.) says: ‘The companions of Imam (a.t.f.s.) who would be busy worshipping or may be resting on their beds will immediately respond to Imam’s (a.t.f.s.) earnest call and rush towards him in a jiffy. They will meet their Imam between Rukne Yamani and Maqame Ibrahim.’ ( ref : Behar v 53 pg 7)
2) Aban bin Taghlib that he said: Abu Abdillah (a.s.) said: “The first to pledge allegiance to Qaim (a.s.) is Jibraeel who would come down in the form of a white bird and give him oath of allegiance. Then keeping one foot on the Holy Kaaba and another on the Holy Qods issue such a loud call that when the creatures hear it they would cry:
“Allah’s commandment has come, therefore do not desire to hasten it.(sure Nahl :1)
“Very soon 313 persons will come to your Masjid – that is the Masjid of Mecca – the people of Mecca will know that they are not natives. All of them will be carrying swords and each of the swords will be inscribed with the Kalima from each of which a hundred Kalimas will be coming out. Then the Almighty Allah shall send a breeze that shall call out in every valley, ‘This is Mahdi, who shall judge like Prophet Dawood and Sulaiman and he would not ask for evidence.’”(ref : Kamaluddin vol 2 chp 58 tdn no 9-10)
3)Aban bin Taghlib that he said: Abi Abdullah (a.s.) said:“As if I can see the Qaim astride a black speckled horse which has a white mark between its eyes. When his horse moves no one will remain in any town who does not think that he is in that town. When he waves the flag of the Messenger of Allah (s.a.w.s.) 13000 angels will come down to him. Of them 13 will be awaiting for the Qaim. These angels are same who were with Prophet Nuh (a.s.) in his Ark, who were with Prophet Ibrahim (a.s.) when he was thrown into the fire and who were with Prophet Isa (a.s.) when he was taken up to the heavens. And 4000 will be following him with flags. 313 are those angels who were present in the Battle of Badr and 4000 are those who came down to accompany Imam Husain (a.s.) in fighting against the Yazidite forces. However they were not allowed to take part in the battle. So they returned to Allah to take the permission but when they came down once more Imam Husain (a.s.) was already martyred. Thus today they remain with disheveled hair and dust smeared condition at the grave of Imam Husain (a.s.) where they will continue to lament till the Judgment Day. And there is constant coming and going of angels between the grave of Imam Husain (a.s.) and the heavens. (ref : Kamaluddin vol 2 chp 58 tdn no 13)
