It seems you can not differentiate between the matn and the sharh of Ibn Nujaym. What you quoted was from the matn of Kanz by Nasafi. Learn the difference. Also, where in the bolded parted does Nasafi conclude that it is recommended to place the hands on the chest? And how can you say this is from a Hanafi point of view while he is talking about the istidlal of the Shafi'iyya?
