294 - وَبِإِسْنادِهِ عَنْ عَلِيِ a.sُ قالَ: قالَالنَّبِيُ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: لا تَذْهَبُ الدُّنْيا حَتّى يَقُومَ رَجُلٌ مِن وُلْدِ الحُسَيْنِ يَملَؤُها عَدْلاً كَما مُلِئَتْ ظُلْماً وَجَوراً.

31-294 According to the same documentation on the authority of Ali , the Prophet (S) said, “The world will not end until one from the progeny of Al-Husayn rises and spreads justice all over the world which oppression and force have covered up with darkness.”
