And if you forget which prayer you prayed and do not know if it was two, three, or four rak'ahs, then pray two rak'ahs, three rak'ahs, or four rak'ahs. If it was Dhuhr, Asr, or Isha, you have prayed four. If it was Maghrib, you have prayed three. If it was Fajr, you have prayed two. And if you spoke during your prayer by mistake, such as saying, "Straighten the rows," then complete your prayer and perform two prostrations of forgetfulness.
