Talbiya and Ihram with head-hair matted (with resin or the like)

Narrated Salim from his father:

I heard that Allah's Apostle assumed Ihram with his hair matted together.

حَدَّثَنَا أَصْبَغُ، أَخْبَرَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ أَبِيهِ ـ رضى الله عنه ـ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يُهِلُّ مُلَبِّدًا.
