Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that when the Messenger of Allah (peace and blessings be upon him) supplicated, he would keep the inner side of his palms towards his face.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Khusayf except Muhammad bin Ishaq; Abbad bin al-Awwam is alone in narrating it."
