As we will see later (Ahadith) the experts of religion are the Masomeen -asws ...

عَلِيُّ بْنُ مُحَمَّدٍ عَنْ بَعْضِ أَصْحَابِنَا عَنِ الْخَشَّابِ عَنِ الْعَبَّاسِ بْنِ عَامِرٍ عَنْ رَبِيعٍ الْمُسْلِيِّ عَنْ يَحْيَى بْنِ زَكَرِيَّا الْأَنْصَارِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ع قَالَ سَمِعْتُهُ يَقُولُ مَنْ سَرَّهُ أَنْ يَسْتَكْمِلَ الْإِيمَانَ كُلَّهُ فَلْيَقُلِ الْقَوْلُ مِنِّي فِي جَمِيعِ الْأَشْيَاءِ قَوْلُ آلِ مُحَمَّدٍ فِيمَا أَسَرُّوا وَ مَا أَعْلَنُوا وَ فِيمَا بَلَغَنِي عَنْهُمْ وَ فِيمَا لَمْ يَبْلُغْنِي Ali ibn Mohammed has narrated from certain person of our people from al-Khashshab, who from al-Abbas ibn Amir from Rabi al-Musalli, who from Yahya ibn Zakariaya al-Ansari who has said the following: I heard Abu Abd Allah -asws say: Whoever loves to have a complete Eman [53] must say: ‘Everything that I say is from the family of Mohammed -asws , whatever they kept secret or made public, whatever has reached me from them and that what has not reached me .

[54] The Difference Between the Ijtihad and Following Ahadith: As per Shia Ijtihad, none of the deeds will be accepted without the taqleed of a non-masoom Mujtahid, however, on the contrary, the Divine Message is: if one does not do the Taqleed of the Holy Infallibles -asws , his/her deeds will be rejected. يَا أَيُّهَا الَّذِينَ آمَنُوا أَطِيعُوا اللَّهَ وَأَطِيعُوا الرَّسُولَ وَلَا تُبْطِلُوا أَعْمَالَكُمْ O you who believe!
