Messenger of Allah (S) said: "As-Salat is two and two, with a Tashahhud for every two Rakʿah, with humility, imploring, having a sense of tranquility, pleading and showing helplessness and stretching out your hand" - he said: raising them - "to your Lord, with the insides of them facing your face, saying: 'O Lord! O Lord! And whoever does not do this, then it is like this or that."  

قَالَ رَسُولُ اللَّهِ ﷺ الصَّلاَةُ مَثْنَى مَثْنَى تَشَهَّدُ فِي كُلِّ رَكْعَتَيْنِ وَتَخَشَّعُ وَتَضَرَّعُ وَتَمَسْكَنُ وَتَذَرَّعُ وَتُقْنِعُ يَدَيْكَ يَقُولُ تَرْفَعُهُمَا إِلَى رَبِّكَ مُسْتَقْبِلاً بِبُطُونِهِمَا وَجْهَكَ وَتَقُولُ يَا رَبِّ يَا رَبِّ وَمَنْ لَمْ يَفْعَلْ ذَلِكَ فَهُوَ كَذَا وَكَذَا
