Muwatta Malik 511
The Qur'an
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، قَالَ اللَّهُمَّ اجْعَلْنِي مِنْ أَئِمَّةِ الْمُتَّقِينَ .
Yahya related to me from Malik that he had heard that Abdullah ibn Umar said, "O Allah, make me one of the leaders of the people of taqwa ." Allahumma jalniy min a'imati'l-mutaqin
