[Machine] The Messenger of Allah ﷺ said, "The zakah of a fetus is due when the zakah of its mother is due, but it is not to be slaughtered until it reaches the age where it contains blood." This is a significant topic discussed through various narrations attributed to Abu Sa'id. However, they have not been explicitly mentioned by him, and it is possible that some people mistakenly believe that the narration of Abu Ayyub is authentic, whereas it is not. Adh-Dhahabi remained silent about it in his summary.  

قَالَ رَسُولُ اللَّهِ ﷺ «ذَكَاةُ الْجَنِينِ إِذَا أُشْعِرَ ذَكَاةُ أُمِّهِ وَلَكِنَّهُ يُذْبَحَ حَتَّى يَنْصَابَّ مَا فِيهِ مِنَ الدَّمِ» هَذَا بَابٌ كَبِيرٌ مَدَارُهُ عَلَى طُرُقِ عَطِيَّةَ عَنْ أَبِي سَعِيدٍ لِذَلِكَ وَلَمْ يُخَرِّجَاهُ وَرُبَّمَا تَوَهَّمَ مُتَوَهِّمٌ أَنَّ حَدِيثَ أَبِي أَيُّوبَ صَحِيحٌ وَلَيْسَ كَذَلِكَ سكت عنه الذهبي في التلخيص
