Al-Saffar from Ibrahim ibn Hashim from Nuh ibn Shu'ayb from Hariz from Muhammad ibn Muslim or Zurarah: It was said: “The prayer over the deceased (Salat al-Mayyit) after he has been buried is merely supplication (du'a).” He (narrator) said: “I asked, ‘Did the Prophet صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family, not pray over al-Najashi?” Imam عليه السلام said: “No, He صلى الله عليه وعلى آله وسلم only supplicated for him.”
