(a) Sayyidah Aishah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The two prostrations of forgetfulness suffice for every addition and deficiency."
(b) In the narration of Ibn Abdan: "The two prostrations of forgetfulness are for every addition and deficiency."
This hadith is counted among the singular narrations of Hakim bin Nafi' al-Raqqi, and Yahya bin Ma'in used to declare him thiqah (trustworthy). And Allah knows best.
