Musannaf Ibn Abi Shaybah

Hazrat Khalid says that I saw Hazrat Abu Qalabah wearing a cloak and a washed garment; he had taken the sheet in the manner of Ihram and had kept his right hand outside of it.

Ibn Aun narrates that Hasan was asked, "People say that it is disliked for a person offering prayer to take his hand out from under his neck." Hasan replied, "If Allah had entrusted the religion to these people, they would have created hardships for His servants!"

Hazrat Hayan bin Umair says that I was with Qais bin Abad. He saw a man who was praying with his hands placed under his neck. He said, "Go to this companion of yours and tell him to remove his hand from the place as if it were in shackles." I went to him and told him that Hazrat Qais is saying to remove your hand from the place as if it were in shackles. So he removed his hand from there.

Hazrat Ibrahim bin Maisarah says that I saw Hazrat Tawus praying in such a way that he had passed his sheet under his shoulder.
