730. hadíth
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «أَيُّ بَعِيرٍ حُجَّ عَلَيْهِ ثَلاَثَ سِنِينَ يُجْعَلُ مِنْ نَعَمِ اَلْجَنَّةِ » وَ رُوِيَ «سَبْعَ سِنِينَ ».
Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "Any camel on which Hajj is performed for three years will be counted among the livestock of Paradise." In another narration, it is reported as "seven years."
