How to perform Salat ut-Tasbih

Rasulullah ﷺ once said to his uncle Hadrat 'Abbas رضی ٓاللہ عنہ : O Abbas! O my uncle! Shall I not give you a gift? Shall I not show you something by means of which Allah will forgive your sins, the first and the last of them, the past and recent, the unintentional and the intentional, the small and huge, the secret and open? Rasulullah ﷺ then taught him the Salah al-Tasbih. Furthermore he advised him that it be offered daily, if possible. If not then every Friday or once a month or once a  year or at least once in one's life time. - (Abu Dawood)

This prayer consists of 4 rak’ah and should be performed everyday. Makruh times should be avoided for this salah. The Tasbih which is to be read in this prayer at different positions is as follows:

Subhanallahi wal hamdulillahi walaa ilaaha ilalahu walahu akbar
(Glory is to Allah! And praise is to Allah! There is no deity save Allah and Allah is the Greatest)

The tasbih is recited 75 times in each rak’ah i.e. 300 times in the entire salah. There are two methods and one can opt for either of the two methods.

First Method

In “Heavenly Ornaments” this method is stated:

Make the intention, say “Allahu Akbar” and fold hands. Recited Surah Fatihah and another Surah.

For the second rak’ah repeat the tasbih in the postures stated above and same will be for the third and fourth rak’ah.
