فَإِذَا رَفَعَ رَأْسَهُ مِنَ السَّجْدَةِ الثَّانِيَةِ فِي الرَّكْعَةِ الثَّانِيَةِ افْتَرَشَ رِجْلَهُ الْيُسْرَى، وَنَصَبَ الْيُمْنَى نَصْبًا، وَوَجَّهَ أَصَابِعَهُ نَحْوَ الْقِبْلَةِ، وَوَضَعَ يَدَيْهِ عَلَى فَخِذَيْهِ، وَبَسَطَ أَصَابِعَهُ، ثُمَّ يَتَشَهَّدُ.
Meaning: After rising from the second prostration of the second rakah, sit upon the laid-down left foot, keep the right foot upright and its toes toward the qiblah, place both hands on the thighs with the fingers extended, then recite the tashahhud.
This is the iftirash form of sitting.
