Muwatta Malik 737
موطأ مالك#737SahihThese are the words of a Companion, not of the Prophet ﷺ. The chain is graded on its own terms.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يُصَلِّي فِي مَسْجِدِ ذِي الْحُلَيْفَةِ
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to pray in the mosque of Dhu'l-Hulayfa, and then go outside and get on his camel and when his camel had stood up he would begin to do talbiya
