Mustadrak al-Hakim — Hadith 1212

Abu Wahb Muhammad bin Muzahim narrates: I asked Abdullah bin al-Mubarak about the prayer (Salat al-Tasbih) in which glorifications are recited. He said: Say the takbir, then say: 'Subhanaka Allahumma wa bi-hamdika, wa tabaraka ismuka, wa ta'ala jadduka, wa la ilaha ghayruka' (Glory be to You, O Allah, and with Your praise; blessed is Your Name, exalted is Your majesty, and there is no god besides You). Then say fifteen times: 'Subhan Allah, wa al-hamdu lillah, wa la ilaha illa Allah, wa Allahu akbar' (Glory be to Allah, all praise is for Allah, there is no god but Allah, and Allah is the Greatest). Then, after seeking refuge (ta'awwudh), recite Surah al-Fatihah and some other surah, then (before bowing) say these glorifications ten times; then ten times in the bowing; then ten times after raising the head from the bowing; then ten times in the prostration; then ten times after raising the head from the prostration (in the sitting); then ten times in the second prostration; and then ten times after raising the head from the prostration (while sitting). Pray four rak'ahs in this way, so there will be seventy-five glorifications in each rak'ah, and thus the total will come to three hundred. If you pray this prayer at night, then in my view it is better that you give the salam after every two rak'ahs; and if you pray it by day, it is up to you whether you give the salam or not.
All the narrators who narrate this hadith from Ibn al-Mubarak are trustworthy (thiqah) and reliable, and Abdullah bin al-Mubarak cannot be suspected of teaching something whose chain was not sahih in his view.
