Kohl for one in Ihram

It was narrated from Abn bin 'Uthman that his father said:

'the messenger of Allah said concerning a Muhrim whose head or yes hurt: 'Let him smudge them with aloes, (sahih):

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ بْنِ مُوسَى، عَنْ نُبَيْهِ بْنِ وَهْبٍ، عَنْ أَبَانَ بْنِ عُثْمَانَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ فِي الْمُحْرِمِ " إِذَا اشْتَكَى رَأْسَهُ وَعَيْنَيْهِ أَنْ يُضَمِّدَهُمَا بِصَبِرٍ " .
