وَلِمُسْلِمٍ عَنْ عَائِشَةَ نَحْوَهُ, وَقَالَ: «سَجْدَةً» بَدَلَ «رَكْعَةً». ثُمَّ قَالَ: وَالسَّجْدَةُ إِنَّمَا هِيَ اَلرَّكْعَةُ
Muslim reported the same above Hadith in another version narrated by 'Aishah (RA), who narrated 'Sajdah (prostration)' instead of 'Rak'a (prayer unit)' and then he (Muslim) said:
“A Sajdah implies a Rak'a.”
