Reward for Visiting Any of the Imams

Here is a Ṣaḥīḥ (Authentic) ḥadīth that says that visiting any of the A’immah (عليهم السلام) is like the reward for visiting al-Husayn (عليه السلام). This means the reward for visiting any of the A’immah (عليهم السلام) is the same as the reward for visiting Imām al-Ḥusayn (عليه السلام).

مُحَمَّدُ بْنُ عَلِيِّ بْنِ الْحُسَيْنِ فِي ثَوَابِ الْأَعْمَالِ عَنْ أَبِيهِ عَنْ سَعْدِ بْنِ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللَّهِ الْبَرْقِيِّ عَنِ الْحَسَنِ بْنِ عَلِيٍّ الْوَشَّاءِ قَالَ قُلْتُ لِلرِّضَا ع مَا لِمَنْ أَتَى قَبْرَ أَحَدٍ مِنَ الْأَئِمَّةِ ع قَالَ لَهُ مِثْلُ مَا لِمَنْ أَتَى قَبْرَ أَبِي عَبْدِ اللَّهِ ع قُلْتُ مَا لِمَنْ زَارَ قَبْرَ أَبِي الْحَسَنِ ع قَالَ مِثْلُ مَا لِمَنْ زَارَ قَبْرَ أَبِي عَبْدِ اللَّهِ ع
From al-Ḥasan bin `Alī al-Washshā‘ said, I said to al-Riḍā (عليه السلام), ‘What is (the reward) for one who comes to the grave of one of the A’immah (عليهم السلام)?’ He (عليه السلام) said to him: ‘Like what is (the reward) of the one who comes to the grave of Abī `Abd Allāh (al-Ḥussayn).’ I (al-Washshā’) said: ‘What is (the reward) for the one who visits the grave of Abī al-Ḥasan (Mūsa al-Kādhim)?’ He (عليه السلام) said: ‘Like what is (the reward) of the one who comes to the grave of Abī `Abd Allāh (al-Ḥusayn)’
