Messenger of Allah 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."  

رَسُولُ اللَّهِ ﷺ مَنْ صَلَّى لِلَّهِ أَرْبَعِينَ يَوْمًا فِي جَمَاعَةٍ يُدْرِكُ التَّكْبِيرَةَ الأُولَى كُتِبَتْ لَهُ بَرَاءَتَانِ بَرَاءَةٌ مِنَ النَّارِ وَبَرَاءَةٌ مِنَ النِّفَاقِ
