“I once was in the company of abu ‘Abd Allah (a.s.), when people on donkey backs passed by. He (the Imam) asked, ‘Where do they want to go?’ I replied, ‘They want to visit the graves of the martyrs.’ He (the Imam) then said, ‘What prevents them from visiting the martyr whom no one helped?’ A man from Iraq then asked, ‘Is visiting him obligatory?’ He (the Imam) said, ‘Visiting him is more virtuous than Hajjah and ‘Umrah, ‘Umrah and Hajjah’, until he counted up to twenty Hajjah and ‘Umrah. Then he said, ‘All accepted, well-performed.’ By Allah, I had not stood up that another man came and said to him, ‘I have performed nineteen times al-Hajj. Pray for me so, He grants me the opportunity to perform twenty times al-Hajj.’ He (the Imam) asked, ‘Have you visited the gravesite of al-Husayn (a.s.) ?’ The man replied, ‘No, I have not done so.’ He (the Imam) said, ‘Visiting al-Husayn (a.s.), is more virtuous than twenty times performing al-Hajj.’”
