Different forms of prostration of forgetfulness
Hadith 685
- " إذا صلى أحدكم فلم يدر كيف صلى؟ فليسجد سجدتين وهو جالس ".
Iyad bin Hilal says: I asked Sayyiduna Abu Sa'id: A man performs prayer but (due to forgetfulness) he does not know how many units he has prayed? He said: The Messenger of Allah (peace and blessings be upon him) said: "When any one of you performs prayer and does not know how many units he has prayed, then while sitting, he should perform two prostrations."
