[Machine] Fatimah, the daughter of Asad son of Hashim, was the first Hashemite born from Hashim's family. She held a high position among the people during the time of the Prophet ﷺ. She passed away during the lifetime of the Prophet ﷺ, and he prayed for her. Her name was Ali, Asad, and because of that, the poem [Al-Bahr Ar-Rajz] says, "I am the one whom my mother called Haydar."  

كَانَتْ فَاطِمَةُ بِنْتُ أَسَدِ بْنِ هَاشِمٍ أَوَّلَ هَاشِمِيَّةٍ وُلِدَتْ مِنْ هَاشِمِيٍّ وَكَانَتْ بِمَحَلٍّ عَظِيمٍ مِنَ الْأَعْيَانِ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ وَتُوُفِّيَتْ فِي حَيَاةِ رَسُولِ اللَّهِ ﷺ وَصَلَّى عَلَيْهَا وَكَانَ اسْمُ عَلِيٍّ أَسَدًا وَلِذَلِكَ يَقُولُ [البحر الرجز] أَنَا الَّذِي سَمَّتْنِي أُمِّي حَيْدَرَهْ
