What is the ruling if a trustworthy narrator with a tendency toward error contradicts another trustworthy narrator?

The questioner : Regarding the addition by a trustworthy narrator, which is accepted under its conditions, if the addition is only by the trustworthy narrator, meaning if the narrator is hasan, i.e., a trustworthy narrator with a tendency toward error or something like that, and he contradicts in this state, meaning another trustworthy narrator, does this rule apply in the same way?

The Shaykh : The contradicting narrator is a trustworthy narrator with a tendency toward error, and the one being contradicted?

The questioner : Trustworthy.

The Shaykh : Is that so, or not?

The questioner : Yes, the rank is hasan, meaning.

The Shaykh : No, you take and give, but I am asking and you are answering.

The questioner: Yes.

The Shaykh : The contradicting narrator is a trustworthy narrator with a tendency toward error, and the one being contradicted is like him or higher than him? If he is like him, the rule applies. If the one being contradicted is higher and more noble, there is no contradiction here that is considered; the hadith described as "trustworthy with a tendency toward error" is set aside, and the hadith whose narrator is described as merely "trustworthy" is relied upon.

The questioner : Meaning, the rule is that the addition of the acceptable is an addition, not the addition of the trustworthy in this state.

The Shaykh : Yes, meaning the addition of the trustworthy is accepted under its condition. What is the condition?
The student : The first is acceptable and the second is rejected.

The Shaykh : Ah, the addition of the trustworthy is acceptable. You indicated the condition.

The questioner : Under its conditions, meaning not directly.

The Shaykh : Very good. The same conditions apply to the narrators of hasan hadiths, meaning a narrator of a hasan hadith who uniquely adds an addition that another narrator of this kind did not narrate, and this unique addition was not narrated by the other. Fine, is there anyone with either group? If we assume they are equal in precision, then if there is something with one of the groups that supports it, it becomes the stronger position. If not, then at that point it depends on the opinion of al-Hafiz Ibn Hajar al-Asqalani on the subject of preference, because he says in the chapter on differing hadiths: "When the acceptable hadith comes, and two hadiths from the category of the acceptable come differing, it is obligatory to reconcile them by one of the ways of reconciliation." He finds the speech, as is his custom, regarding the ways of reconciliation. Al-Hafiz al-Iraqi brought them to more than a hundred ways in his commentary on the introduction of Ibn al-Salah. The Hafiz points out and says it is obligatory to reconcile, because the two acceptable hadiths are for one of the ways of reconciliation. He means the acceptable, hasan and above. He said: "If reconciliation between the two hadiths is not possible, it is referred to considering the abrogating and the abrogated." He said: "If it is not possible," meaning the earlier and later date is not known, it is not known, so it is referred to. And here is the point: "It is referred to preference." What does preference mean? A hasan is opposed by a sahih, so the hasan is left and the sahih is taken. A sahih, single, and strange is opposed by a sahih, widespread, or famous, so the single sahih is left, and so on. The famous or widespread sahih is contradicted by a hadith that is mutawatir, so this is taken and that is left. The point is what came after now comes. He said: "He said, if they are equal." If they are equal, reconciliation is not possible, considering the abrogating and the abrogated is not possible, and preference is not possible due to their equality in strength, "and the matter is left to its scholar and the researcher suspends judgment." The researcher suspends judgment and entrusts the matter to its scholar. I say from my own view, and I will not say as the later Hanafis say that they contradict and fall away...

The questioner : ... The hadith of qunut in witr, is it a hasan hadith or a sahih one?

The Shaykh : You mean the hadith of al-Hasan ibn 'Ali.

The questioner: Yes.

The Shaykh: All right.

The questioner : It is a hasan hadith, as I believe Ibn Hajar grades it as hasan.

The Shaykh : By Allah, what is in my mind is that it is sahih, but let us see what follows from that?

The questioner : I agree with him that the correct is hasan. The addition in al-Nasa'i... so I was surprised by the addition, meaning is al-Hasan, meaning this narration is hasan... hasan, so how was this addition added?

The Shaykh : Is there a contradiction?

The questioner : There is no contradiction, but the addition, according to this rule you mentioned, is correct.
