Al-Husayn ibn Sa‘id, from Fadalah, from Husayn ibn ‘Uthman, from Sama‘ah, from Abu Basir: Abu Abdillah عليه السلام, peace be upon him, said: “If a man forgets to say the salam, then when he turns his face away from the qiblah and says ‘al-salamu ‘alayna wa ‘ala ‘ibadillah al-salihin’, he has completed his prayer."
