The narration that removes the difficulty some people have raised regarding Moses (peace be upon him) striking the Angel of Death.

The Shaykh : Now, after we have clarified that the one who weakened the hadith is the weak one, because he first contradicted the two Imams who compiled the two books known as the "Sahihayn," which, by the consensus of the scholars of the Sunnah, are the most authentic books after the Book of Allah (Blessed and Exalted is He)—namely, "Sahih al-Bukhari" and "Sahih Muslim"—and not only that, but the Ummah accepted them; therefore, no one among the scholars of hadith who were at the level of al-Bukhari and Muslim criticized any hadith found in the "Sahihayn"; so all these hadiths are certainly established from the Prophet (peace and blessings be upon him); therefore, we give no weight to anyone who weakens such a hadith, no matter who he is, and no matter how much knowledge people think he has.
As for the difficulty described in the question: how does Moses (peace be upon him) strike the Angel of Death?
The answer—and this points to what I said, that these people do not study the Sunnah—the answer is: there is a narration in "Musnad al-Imam Ahmad" with a sound chain that says: . So, when the Angel of Death came to Moses, he said to him: "Answer your Lord." He did not come with the sign that would make Moses (peace be upon him) realize that the one saying to him: is an angel sent by Allah; he came to him in the form of a human being. And any one of us, if a person came to him and said: ; what would his stance toward him be?! It would be exactly the stance of Moses (peace be upon him); because he is encroaching on the duty of a noble angel in which the other angels do not share. So how about a person who approaches a human being like him and says: "Surrender your soul"?! So Moses did nothing but strike him, slap him, and pop out his eye. This is a natural reaction. And the doubt falls away and is removed from its root and branch when we remember this other narration: . Therefore, you see in the continuation of the hadith that when the Angel of Death complained of his matter to Allah and said to Him: . When the angel returned with this proof to Moses (peace and blessings be upon him), he said to him: . So he took his soul at that very moment.
Why did he submit the second time and not the first time?
The answer is clear. First, the one demanding it was a human being from among humans, so it was as if he was mocking him, and Moses did not know that he was an angel sent by Allah. Therefore, he struck him. When the angel came with this sign from Allah (Mighty and Majestic), and Moses was reassured by it, and he asked him that question, and he answered: . So Moses does not hate death, but he popped out the man's eye on the assumption that he was a human being from among humans. So when we look at the hadith with the interpretation of this narration that Imam Ahmad narrated in the "Musnad," the difficulty falls away, and the claim of those who said: "Perhaps this hadith is from the Isra'iliyyat" is invalidated. This is a false statement; because when it is said that a certain narration or hadith is from the Isra'iliyyat, that means it is from what the People of the Book, the Jews and the Christians, used to discuss among themselves, some narrations they received from their ancestors, which contain both truth and falsehood. Therefore, he (peace be upon him) said: . This is the meaning of something being from the Isra'iliyyat.
