وَعَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ
قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ كَأَنَّهُ عَلَى الرَّضْفِ حَتَّى يَقُومَ
Abdallah ibn Masud said that in the first two rakas the Prophet (sallallahu alayhi wa sallam) was as though he were on heated stones till he got up.* *A figurative phrase to express the shortening of the sitting during the tashahhud. Tirmidhi, Abu Dawud and Nasai transmitted it.
