It was narrated from Salim, from his father:
“I heard the Messenger of Allah ﷺ reciting the Talbiyah when he entered Ihram with something applied to his head to keep the hair together.’”

حَدَّثَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ الْمِصْرِيُّ، أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَنْبَأَنَا يُونُسُ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، سَمِعْتُ رَسُولَ اللَّهِ ﷺ يُهِلُّ مُلَبِّدًا .
