The Mahdī will be from the Fāṭimah's bloodline

abudawud:4284Aḥmad b. Ibrāhīm > ʿAbdullāh b. Jaʿfar al-Raqqī > Abū al-Malīḥ al-Ḥasan b. ʿUmar > Ziyād b. Bayān > ʿAlī b. Nufayl > Saʿīd b. al-Musayyab > Um Salamah

The Prophet ﷺ said: The Mahdi will be of my family, of the descendants of Fatimah. Abdullah ibn Ja'far said: I heard AbulMalih praising Ali ibn Nufayl and describing his good qualities.  

أبو داود:٤٢٨٤حَدَّثَنَا أَحْمَدُ بْنُ إِبْرَاهِيمَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ الرَّقِّيُّ حَدَّثَنَا أَبُو الْمَلِيحِ الْحَسَنُ بْنُ عُمَرَ عَنْ زِيَادِ بْنِ بَيَانٍ عَنْ عَلِيِّ بْنِ نُفَيْلٍ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ أُمِّ سَلَمَةَ قَالَتْ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الْمَهْدِيُّ مِنْ عِتْرَتِي مِنْ وَلَدِ فَاطِمَةَ قَالَ عَبْدُ اللَّهِ بْنُ جَعْفَرٍ وَسَمِعْتُ أَبَا الْمَلِيحِ يُثْنِي عَلَى عَلِيِّ بْنِ نُفَيْلٍ وَيَذْكُرُ مِنْهُ صَلاَحًا
