I heard my father saying, "Never did Messenger of Allah ﷺ assume Ihram except at the Mosque, that is, at the Mosque of Dhul-Hulaifa.  

أَنَّهُ سَمِعَ أَبَاهُ يَقُولُ مَا أَهَلَّ رَسُولُ اللَّهِ ﷺ إِلاَّ مِنْ عِنْدِ الْمَسْجِدِ يَعْنِي مَسْجِدَ ذِي الْحُلَيْفَةِ  

Yahya related to me from Malik from Musa ibn Uqba that Salim ibn Abdullah heard his father say, "Your claim that the Messenger of Allah ﷺ entered ihram from this desert of yours is not true, because he only entered ihram from the mosque, i.e. the mosque of Dhu'l-Hulayfa."  

يَقُولُ بَيْدَاؤُكُمْ هَذِهِ الَّتِي تَكْذِبُونَ عَلَى رَسُولِ اللَّهِ ﷺ فِيهَا مَا أَهَلَّ رَسُولُ اللَّهِ ﷺ إِلاَّ مِنْ عِنْدِ الْمَسْجِدِ يَعْنِي مَسْجِدَ ذِي الْحُلَيْفَةِ  

Ibn ʿUmar said this is your al-Baida’ about which you ascribe falsehood to the Messenger of Allah (SWAS). He did not raise his voice in talbiyah but from the masjid, i.e. the mosque of Dhu al-Hulaifah. (Using translation from Abū Dāʾūd 1771)   

الْبَيْدَاءُ الَّتِي تَكْذِبُونَ فِيهَا عَلَى رَسُولِ اللهِ ﷺ مَا أَهَلَّ رَسُولُ اللهِ ﷺ إِلَّا مِنْ عِنْدِ مَسْجِدِ ذِي الْحُلَيْفَةِ  

"أَنَّ النَّبِيَّ ﷺ أَهَلَّ منْ مَسْجِدِ ذِى الْحُلَيْفة".
