Muwatta Malik, Book 7, Hadith 27 (USC-MSA) ⓘ
Yahya related to me from Malik that Abd ar-Rahman ibn al-Qasim said, "I heard Abdullah ibn Amir ibn Rabia say, 'I sometimes pray witr while hearing the iqama, or after the break of dawn.' " Abd ar-Rahman was not certain which he said.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، أَنَّهُ قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَامِرِ بْنِ رَبِيعَةَ، يَقُولُ إِنِّي لأُوتِرُ وَأَنَا أَسْمَعُ الإِقَامَةَ، أَوْ بَعْدَ الْفَجْرِ . يَشُكُّ عَبْدُ الرَّحْمَنِ أَىَّ ذَلِكَ قَالَ .
