Hadith 285
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، فَاتَتْهُ رَكْعَتَا الْفَجْرِ فَقَضَاهُمَا بَعْدَ أَنْ طَلَعَتِ الشَّمْسُ .
Yahya related to me from Malik that he had heard that Abdullah ibn Umar missed the two rakas of dawn, and then did them after the sun rose
