Chapter 17: Completing what is Recalled When Uncertain how much has been Prayed
Muwatta Malik 217
Yahya related to me from Malik from Nafi that Abdullah ibn Umar, when questioned about forgetfulness in the prayer, said, "If you think that you have forgotten part of the prayer, then pray it."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا سُئِلَ عَنِ النِّسْيَانِ، فِي الصَّلاَةِ قَالَ لِيَتَوَخَّ أَحَدُكُمُ الَّذِي يَظُنُّ أَنَّهُ نَسِيَ مِنْ صَلاَتِهِ فَلْيُصَلِّهِ .
