Hanafis forbid 7 parts of meat is there any proof from Hadith for example, the blood, the penis, the reticules.

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Some of Hanafi scholars clearly gave a decree that it is dislikeable to use seven things from the slaughtered Halal animal.
The author of al-Jawharah al-Nayyirah wrote: 'The Prophet (Sallallahu Alaihi wa Sallam) disliked seven parts from a slaughtered animal: Penis, testicles, sex organs, glands, gallbladder, urinary bladder and blood' .
Another narration adds: "The anus" as in al-Yanabi' Book.
Imam Abu Hanifa said: 'Blood is forbidden for the clear evidence of Sharia, the other six mentioned organs are dislikeable since a human being naturally dislikes and detests them, Allah knows best' .
Some Hanafi scholars even considered them Haram. See, 'Badaie wa al-Saraie'. However, both opinions could be unified by saying that they are strongly dislikeable, i.e. Karaha Tahreem.
They relied in this ruling on the Hadith mentioned above. The Hadith is Mursal and reported by Imam al-Baihaqi . Imam al-Nawawi considered it weak in his book 'Sharah al-Muhazzab'.
Blood is forbidden for the verse: {Forbidden to you (for food) are: Al-Maytatah (the dead animals - cattle-beast not slaughtered), blood, …} [5: 3].
In addition, all the Muslim scholars have agreed that the blood is forbidden.
Muslim scholars have different opinions regarding the remaining six organs.
Shafi'yah also considers them just dislikeable.
Allah knows best.
