Malik Muwattaوَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، وَزَيْدَ بْنَ ثَابِتٍ، كَانَا يَقُولاَنِ مَنْ أَدْرَكَ الرَّكْعَةَ فَقَدْ أَدْرَكَ السَّجْدَةَ .
Yahya related to me from Malik that he had heard that Abdullah ibn Umar and Zayd ibn Thabit used to say, "Whoever catches the ruku has caught the sajda."
