حَدَّثَنَا سَهْلُ بْنُ تَمَّامِ بْنِ بَزِيعٍ، حَدَّثَنَا عِمْرَانُ الْقَطَّانُ، عَنْ قَتَادَةَ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ الْمَهْدِيُّ مِنِّي أَجْلَى الْجَبْهَةِ أَقْنَى الأَنْفِ يَمْلأُ الأَرْضَ قِسْطًا وَعَدْلاً كَمَا مُلِئَتْ جَوْرًا وَظُلْمًا يَمْلِكُ سَبْعَ سِنِينَ ‏"‏ ‏.‏

Narrated AbuSa'id al-Khudri: The Prophet (PBUH) said: The Mahdi will be of my stock, and will have a broad forehead a prominent nose. He will fill the earth will equity and justice as it was filled with oppression and tyranny, and he will rule for seven years. Translation Not Available
