Are the hadiths of the Prayer of Tasbih authentic?

The questioner : To what extent is the Prayer of Tasbih authentic...?

The Shaykh : The Prayer of Tasbih is among the hadiths in which the scholars of hadith have disagreed in a strange manner. Some say that the hadith of the Prayer of Tasbih is fabricated, while others say it is authentic. The cause of this severe disagreement returns to two matters:
The first matter is that this prayer, in reality, has not come with a sound chain of narration that serves as a proof.
The second reason is that it contradicts the form of all the prescribed prayers; thus, it is anomalous from this perspective.
Those who judged it to be fabricated looked at these two facts: that it has no sound chain of narration that serves as a proof, and that the text contradicts all the prayers established by the Sunnah.
However, those who held the view that it is authentic, or at least good, have the perspective that it is true that this prayer, or the hadith of Tasbih, does not have an independent sound chain of narration. But it has many routes, and from the rules of the scholars of hadith, a weak hadith is strengthened by the multiplicity of its routes. This hadith has routes that strengthen it. This is from one side. From another side, it is established from some of the Salaf, specifically 'Abd Allah ibn al-Mubarak, who was one of the great shaykhs of Imam Ahmad (peace and mercy of Allah and His blessings be upon him). He used to go to the extent of praying it, so he would perform it. It is far-fetched for such an Imam to act upon a hadith that is not established for him.
So, if we look at this collection, the summary of which is that the hadith of the Prayer of Tasbih came from routes that strengthen one another, and additionally, 'Abd Allah ibn al-Mubarak used to pray it, then the soul is reassured at that time of the authenticity of the hadith, and consequently, the legitimacy of praying it. At that time, the doubt mentioned earlier, which was related as a report from those who said it is not authentic, is refuted. The claim was that similarity in some prayers is not required to be present. Because we know that there is a prayer that is authentic by the consensus of the scholars, and yet it differs from all the prayers. At the same time, the Prayer of Tasbih aligns with all the prayers from this direction. I mean: the prayer that contradicts all the prayers is the eclipse prayer. We all know that in the eclipse prayer, it is prescribed to have two bowings in every rak'ah, as it is prescribed to have two prostrations. So, from the fact that it is prescribed to have two bowings in the single rak'ah of the eclipse prayer, it has contradicted all the known prayers from this perspective, because there is no other prayer in which it is prescribed to have two bowings in the single rak'ah. So, was the existence of such a contradiction to the five prayers and others a reason to criticize the authenticity of the hadith? The answer is: No. Because Allah (Blessed and Exalted is He) has the right to prescribe for His servants whatever He wills of prayers and forms. So, the criterion is not that the act of worship has similar counterparts, but rather that it is established by the routes that establish all acts of worship. If we leave this aspect of criticism, which is the criticism of the text of the Prayer of Tasbih, and return to the chains of narration, and we know that some of them strengthen one another, and that some of the Salaf acted upon it, then at that time, there remains no valid face for the criticism of the form of this prayer. Then, the statement of those who said that the hadith of the Prayer of Tasbih is established stands, and consequently, the establishment of worshipping with it, at least once in a lifetime as mentioned in the hadith itself, and at most once every day.
This is what I have in answer to this question.
