The renowned scholar of the Ahlus Sunnah, Ibn Abil Hadid in his commentary of Nahjul Balaghah relates that on the day of the Victory of Makkah which took place in the sixth year of the migration (Hijrah), a man named Hubar b. al-Aswad frightened Zaynab, the daughter of the Prophet, who was seated in the camel litter, due to which the child in her womb was aborted.
Due to this act, the Prophet declared it lawful to shed the blood of Hubar.
Ibn Abil Hadid further says that, “I related this incident to my teacher Abu Ja’far al-Naqib and he replied, ‘If the Prophet considered the shedding of the blood of Hubar b. al-Aswad to be lawful because he frightened Zaynab through which her child was miscarried, then it proves that if he would have been alive, he would have considered lawful shedding the blood of the one who had frightened Fatimah and due to which her child was miscarried.’
I asked him, ‘Then should I relate this through your authority that Fatimah was frightened and that her son, Muhsin was miscarried?’
Abu Ja’far al-Naqib replied, ‘Do not narrate it’s accuracy nor it’s inaccuracy on my authority, while I am neutral regarding it and I refuse to speak out regarding it due to some reports present with me.’
