Hadith 4193 وَ عَنْهُ عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ سِنَانٍ قَالَ سَمِعْتُ الرِّضَا (ع) يَقُولُ زِيَارَةُ قَبْرِ الْحُسَيْنِ (ع) تَعْدِلُ عُمْرَةً مَبْرُورَةً مُتَقَبَّلَةً
3. Muḥammad ibn Ja’far narrated to me from Muḥammad ibn Ḥusain, from Muḥammad ibn Sinān, who said: I heard Imam Riďā (a.s.) say: Going to the Ziyārah of the grave of Ḥusain (a.s.) is equal to performing a purified and accepted ‘Umrah.
