1112. hadíth
وَ كَتَبَ أَبُو عَبْدِ اَللَّهِ اَلْبَرْقِيُّ إِلَى أَبِي جَعْفَرٍ اَلثَّانِي عَلَيْهِ اَلسَّلاَمُ: أَ يَجُوزُ جُعِلْتُ فِدَاكَ اَلصَّلاَةُ خَلْفَ مَنْ وَقَفَ عَلَى أَبِيكَ وَ جَدِّكَ عَلَيْهِ اَلسَّلاَمُ فَأَجَابَ «لاَ تُصَلِّ وَرَاءَهُ.
Abu Abdullah al-Barqi wrote to Abu Ja'far al-Thani (a.s), asking: "May I be your ransom, is it permissible to pray behind someone who stopped at (only accepted the Imamate of) your father and grandfather (a.s)?" Imam (a.s) said: "Do not pray behind him."
