as salam alaikum
Salat al-Tasbih is known by some as "Salat Ja'far al-Tayyar" because it is said that it was taught by the Prophet, peace be upon him and his family, to his cousin Ja'far. Some reports state that it was taught to Abbas Ibn Abdul-Muttalib as well. This salat has been mentioned in many books. Amongst them:
- "al-Kafi" by Shaykh al-Kulayni
- "Man la Yahduruhu al-Faqih" by Shaykh al-Saduq
- "Tahdib al-Ahkam" by Shaykh al-Tusi
- "Sunan Abi Dawud"
- "Sunan al-Tirmidhi"
- "Sunan Ibn Majah"
It has been reported through different chains of transmission with slight variations that do not alter its integrity. It has also been reported by ulama belonging to different schools and practiced by the Imam of Ahl al-Bayt and many pious predecessors. Such widespread practice strengthens the hadiths transmitted on the authority of the Messenger of Allah, peace be upon him and his family.
With prayers for your success.
