1. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar and Muhammad ibn ’Isma‘il from al-Fadl ibn Shadhan all from Safwan ibn Yahya from ibn Muskan from al-Hassan ibn Ziyad al-Sayqal who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘Two pieces of twig are placed with a deceased, one on the right and the other on the left.’ He (the narrator) has said, that he (the Imam) said, ‘Al-Jaridah (twig of palm tree) benefits both, believers and non-believers.’”
