Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) used to look to the right and to the left during prayer, but he would not turn his neck to look behind his back. In narrating this as a connected (muttasil) narration, the narrator named Fadl bin Musa is unique. Other narrators have transmitted it as a mursal narration.
