📚 Al-Kafi, Vol. 6, p. 254

Amir al-Mu'minin (peace be upon him) said: When one of you buys meat, he should remove the glands, as they stimulate the leprosy veins!

6⃣قَالَ أَبَانٌ ثُمَّ قَالَ أَبُو عَبْدِ اللَّهِ یُکْرَهُ مِنَ الذَّبِیحَةِ عَشَرَةُ أَشْیَاءَ مِنْهَا الطِّحَالُ وَ الْأُنْثَیَانِ وَ النُّخَاعُ وَ الدَّمُ وَ الْجِلْدُ وَ الْعَظْمُ وَ الْقَرْنُ وَ الظِّلْفُ وَ الْغُدَدُ وَ الْمَذَاکِیرُ

📚 Al-I‘lāl al-Sharā’i‘, Vol. 2, p. 562

In a narration, Aban bin Uthman said: Imam Sadiq (peace be upon him) said: Ten things from the slaughtered animal are disliked, among them are the spleen, testicles, marrow, blood, skin, bones, horns, hooves, glands, and the male organ!

7⃣ Narrated from Abu Abdullah (peace be upon him): Ten things are forbidden from the slaughtered animal, and ten things are permitted from a dead animal. As for the forbidden from the slaughtered animal, they are blood, dung, glands, spleen, the male organ, testicles, womb, hooves, horns, and hair.

📚 Mahāsin, Vol. 2, p. 471

Imam Sadiq (peace be upon him) said in a narration: Ten things are prohibited from the slaughtered animal. So, the prohibited things are blood, dung, glands, spleen, the male organ, testicles, womb, hooves, horns, and hair.

✅ In the above narrations and others, it is clear that eating certain parts of a lawful slaughtered animal is specifically prohibited, including eating the glands and veins of the slaughtered animal.

✅ However, there is no specific prohibition mentioned regarding the lungs (or liver) or white liver, and it is not part of the general prohibitions such as glands and veins.

Therefore, eating them is not forbidden or disliked in the available narrations, and there is no issue in consuming them.

✅ Why do you not pray more for the hastening of the appearance of ‘Muḥyī Ma‘ālim al-Dīn wa Ahlihi,’ the reviver of the laws and the people of religion?

Let us pray more for the hastening of his appearance:

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