In the name of Allah, the most Beneficent, the most Merciful.
The Prophet of Allah Sallallahu Alahi Wasalam said to his uncle, Saaiduna Abbas Radiallahu Anhu, ‘O uncle! Shall I not give you! Shall I not grant you! Shall I not award you! Shall I not do mercy on you! When you do ten things Allah (SWA) will forgive your sins of the future and of the past, new and old, those you have forgotten those you did knowingly, big and small, hidden and revealed. Then he Sallallahu Alahi Wasalam taught the way to pray Salatul Tasbih and then said if you can pray this salah once a day then every Friday, and even if this is not possible then once a month and even if this is not possible then once a year and even if this is not possible then at least once in a lifetime.” (Sunan Abi Dawud p.190 v.1 & Sunan Tirimizi p.109 v.1)
Imam Tirimizi (RA) says that many scholars like Abdullah Ibn Mubarak (RA) have accepted the virtue of Salatul Tasbih. (Sunan Tirimizi p.109 v.1)
Imam Baihaqi (RA) has said that Salataul Tasbih was the practice of many pious predecessors and this leads to strength in its acceptability. (Shuabul Iman p.472 v.1)
Allahmah Munziri (RA) mentions that many muhadditeen such as Imam Abu Muhammed Al Misiriy, Imam Abu Hasan Maqdisi, Imam Baihaqi, Imam Subki and Imam Nawaai have accepted its authority. (Targheeb Wa Tarheeb p.468 v.1)
The Hanafi Scholars support the view of its acceptance. Imam Subki (RA) and Imam Badrul Deen Zarakashi (RA) have said that it is from the fundamentals of Deen and anyone who discards it is not on the correct path. (Futuhaatur Rabbaaniyah p.321 v.4)
Sheikh Nasir Uddin Albani (RA) has declared the hadith of Sunan Abi Dawud as hasan also. Therefore the conclusion we can come to is that the practice of Salatul Tasbih is not a bidah and those who read it, inshallah will receive the rewards mentioned in the hadith.
