It was narrated that Abu Saeed Al-Khudri said: “We used to estimate how long the Messenger of Allah صلی اللہ علیہ وآلہ وسلم stood when praying in Zuhr and ‘A We estimated that he stood in Zuhr for as long as it takes to recite thirty verses, as long as Sarat As-Sajdah in the first two Rak’ahs, and half that in the last two. And we estimated that he stood for as long in the first two Rak’ahs of ‘Asr as he stood in the last two Rak ‘ahs of uhr, and we estimated that he stood half as long as that in the last two Rak’ahs of ‘Asr.” (Sahih)
