وَعَنْ كَعْبِ بْنِ مُرَّةَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ شَابَ شَيْبَةً فِي الْإِسْلَامِ كَانَتْ لَهُ نُورًا يَوْمَ القيامةِ» . رَوَاهُ التِّرْمِذِيّ وَالنَّسَائِيّ

Kab ibn Murra reported that the Messenger of Allah ﷺ said, “Whoever has a hair turn gray while in Islam, it will be a light for him on the Day of Resurrection.” Al-Tirmidhi and al-Nasai transmitted it.
