Allah's Messenger said: "Whoever performs Salat for Allah for forty days in congregation, catching the first Takbir, two absolutions are written for him: absolution from the Fire, and absolution from the Fire, and absolution from hypocrisy."

Jami` at-Tirmidhi Book 2, Hadith 92 Next Hadith → "When Allah;s Messenger stood for Salat during the night, he would say the Takbir (Allahu Akbar), then say: (Subhanaka Allahumma wa bihamdika wa Tabarakasmuka wa Ta'ala Jadduka wa la ilaha ghairuk.) 'Glorious You are O Allah, and with Your praise, and blesses is Your Name, and exalted is Your majesty, and none has the right to be worshipped but You' Then he would say: (A'udhu Bilahi As-Sami'il-Alimi min Ash-Shaitanir-Rajimi, min Hamzihi Wa Nafkhihi wa Nafthihi.)" 'Allah is undoubtedly the greatest.' (Allahu Akbaru Kabira). Then he would say: 'I seek refuge in Allah the All-Hearing, the All-Knowing, from the cursed Shaitan, from his madness, his arrogance, and his poetry.'
