Musannaf Ibn Abi Shaybah

Hazrat Ibn Muhairiz narrates that the Messenger of Allah, peace and blessings be upon him, said: When you ask Allah, then ask with the inner part of your palms. And do not ask with the back of your palms.

Hazrat Laith narrates that Hazrat Shahr said: Asking (supplication) is done in this manner, and he spread his hands in such a way that the palms were facing his face. And he said: Seeking refuge is done in this manner, and he turned his palms over.

Hazrat Abu Saeed Al-Khudri narrates that the Messenger of Allah, peace and blessings be upon him, was supplicating at the place of Arafah, and he had raised both his hands in such a manner that the outer part of the hand was facing his face, and the inner part of the hand was facing towards the ground.

Hazrat Ibn Abbas (may Allah be pleased with them both) says that sincerity is like this, and he gestured with his finger, and supplicating is like this, that is, with the inner part of both palms, and seeking refuge is like this. Then he raised both his hands and turned their backs towards his face.
