Chapter 84 | The rise of al-Mahdi with Divine Authority earlier or later will not affect one who has learned who his Imam is
3ـ عَلِيُّ بْنُ مُحَمَّدٍ رَفَعَهُ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ قَالَ قُلْتُ لابِي عَبْدِ الله جُعِلْتُ فِدَاكَ مَتَى الْفَرَجُ فَقَالَ يَا أَبَا بَصِيرٍ وَأَنْتَ مِمَّنْ يُرِيدُ الدُّنْيَا مَنْ عَرَفَ هَذَا الامْرَ فَقَدْ فُرِّجَ عَنْهُ لانْتِظَارِهِ.
3. Ali ibn Muhammad has narrated from in a Murfu‘ manner from Ali ibn Hamza from abu Basir who has said the following. “I said to abu ‘Abdallah , “May Allah take my soul in service for your cause, when will relief will come?” The Imam said, “O abu Basir, are you after the worldly gains? In fact, one who has established faith in this matter (the rise of al-Mahdi with Divine Authority) he has already experienced relief of expecting his (coming with Divine Authority).”
