سَأَلْتُ أَبَا الْحَسَنِ الرِّضَا عَلَيْهِ السَّلامُ قُلْتُ لَهُ لايِّ عِلَّةٍ صَارَتِ الإِمَامَةُ فِي وُلْدِ الْحُسَيْنِ دُونَ وُلْدِ الْحَسَنِ عَلَيْهِ السَّلامُ قَالَ لانَّ اللَّهَ عَزَّ وَجَلَّ جَعَلَهَا فِي وُلْدِ الْحُسَيْنِ وَلَمْ يَجْعَلْهَا فِي وُلْدِ الْحَسَنِ وَاللَّهُ لا يُسْئَلُ عَمَّا يَفْعَلُ.
32-17 Ali ibn Ahmad ibn Abdillah ibn Ahmad ibn Abi Abdillah al-Barqi, may God be pleased with him - narrated that his father quoted on the authority of his grandfather, on the authority of Ahmad ibn Abi Abdillah al-Barqi, on the authority of Muhammad ibn Isa that Muhammad ibn Abi Yaqoob al-Balkhi asked Abal Hassan Ar-Ridha’ 
,
“Why is Divine Leadership in the lineage of Al-Husayn, and not that of Al-Hassan?” Ar-Ridha’ replied, “Indeed the Honorable the Exalted God established Divine Leadership in the lineage of Al-Husayn , and God cannot be questioned regarding what He does.”
