Muwatta Malik, Book 20, Hadith 752 (In-Book) ⓘ
Yahya related to me from Malik that Ibn Shihab used to say, "Abdullah ibn Umar would never say the talbiya while he was doing tawaf of the House."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ كَانَ يَقُولُ كَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ لاَ يُلَبِّي وَهُوَ يَطُوفُ بِالْبَيْتِ .
