Hadith 202

(The book) ‘Ikmal Al Deen’ – Ibn Al Waleed, from Al Saffar, from Ibn Abu Al Khattab and Al Yaqteeny, both together from Ibn Abu Najran, ‘From Isa Bin Abdullah Bin Muhammad Bin Umar son of Ali-asws Bin Abu Talib-asws, from his maternal uncle Al-Sadiq Ja’far Bin Muhammad-asws, he (the narrator) said, ‘I said to him-asws, ‘If the inevitable (death) were to happen, and may Allah-azwj not Show me your-asws day, then with whom should I be led? ’
He-asws gestured to Musa-asws. I said to him-asws, ‘Supposing he-asws were to pass away, then to whom? ’ He-asws said: ‘To his-asws son-asws’. I said, ‘If his-asws son-asws passes away and leave an elder brother and a younger son, with whom should I be led? ’ He-asws said: ‘By his-asws son-asws. Then like this, for ever! ’
I said, ‘Supposing I do not recognise him-asws and do not know of his-asws place, then what shall I do? ’
He-asws said: ‘You should say: ‘O Allah-azwj! I befriend the one remaining from Your-azwj Divine Authority, from the sons of the past Imam-asws’. That would suffice you’’. [84]
