[379] Al-Nawawi says: “Our companions say: ‘The wisdom of sitting in iftirash in the first tashahhud and tawarruk in the second is that it is closer to remembering in prayer and not getting confused regarding the number of units prayed. Also, since the sunnah is to keep the first tashahhud brief, one sits in iftirash during it so that it is easier to stand up. The sunnah is to extend the second, and there is no standing after it, so one sits in tawarruk in order that it be more conducive for him and settled such that he might supplicate abundantly. Also, when a latecomer sees him, he knows which of the two tashahhuds he is observing.’” (Al-Majmu’, 3/451) This is the position of the Shafi`i and Hanbali schools.
