that 'Ali mentioned the daughter of Abu Jahl (for marriage), and that reached the Prophet ﷺ so he said: "Indeed Fatimah is but a part of me, I am harmed by what harms her and I am uncomfortable by what makes her uncomfortable." (Using translation from Tirmidhī 3869)
أن عَلِيًّا ذَكَرَ بِنْتَ أَبِي جَهْلٍ فَبَلَغَ ذَلِكَ رَسُولَ اللهِ ﷺ فَقَالَ «إِنَّمَا فَاطِمَةُ بَضْعَةٌ مِنِّي يُؤْذِينِي مَا آذَاهَا وَيُنْصِبُنِي مَا أَنْصَبَهَا»
