✅ Answer: Please consider the following narrations:

1⃣عَنْ عِدَّةٍ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِیَادٍ وَ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِیعاً عَنِ ابْنِ أَبِی نَصْرٍ قَالَ: سَأَلَ رَجُلٌ الرِّضَا عَنِ الزَّوْجِ مِنَ الْحَمَامِ یُفْرِخُ عِنْدَهُ یُزَوَّجُ الطَّیْرُ أُمَّهُ وَ ابْنَتَهُ قَالَ لَا بَأْسَ بِمَا کَانَ بَیْنَ الْبَهَائِمِ.

📚 Al-Kafi, vol. 6, p. 548

Ibn Abi Nasr said: A man asked Imam Reza (peace be upon him) about a pair of pigeons that laid eggs in his care, and the male bird mated with its mother and daughter. The Imam replied: Whatever occurs among animals has no problem!

2⃣قَالَ الصَّادِقُ : كُلُّ شَيْءٍ مُطْلَقٌ حَتَّى يَرِدَ فِيهِ نَهْيٌ

📚 Al-Faqih, vol. 1, p. 317

Imam Sadiq (peace be upon him) said: Everything is permissible by default unless a prohibition is specifically mentioned regarding it!

✅ Based on the above and other narrations, the prohibition of incest applies only to humans. Mating among animals—even with their mothers or offspring—has no religious issue, and there is no narration prohibiting the consumption of meat resulting from such cases. Therefore, eating such meat is permissible.

اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْر
