The statement of Imam Ahmad regarding ablution from vomiting and blood

Question:
And from what? If Imam Ahmad (may Allah have mercy on him) were to bless this hadith, and we would thank him for it, otherwise these are authentic hadiths. Al-Dhahabi narrated from him that after what is in it, Khalid ibn Dhanab came. When he prayed and said the closing salam, the Imam said to him: "You have made your suckling child [perform the prayer]; is that sufficient?" Imam Ahmad (may Allah have mercy on him) said: "Umar came and he was milking a camel as a penalty, so that does not indicate that this is the most recent."

Answer:
This is a second narration, a second narration that Imam Ahmad agrees with the majority. However, the school of thought in the text of al-Zad and others is to act according to what this hadith indicates, not just for the sake of this hadith alone, but because it was reported that the Prophet (peace and blessings be upon him) vomited and then performed ablution. This supports this hadith regarding the condition of ablution from vomiting. Imam Ahmad did not take this hadith alone regarding the condition of vomiting. As for the issue of blood, this is a matter of research. The issue of blood is indeed a matter of research, yes. There is a difference between vomiting and blood. Yes.
