[Machine] The Messenger of Allah ﷺ said, "Do not pluck out gray hair, as it is a light for the Muslim. Every Muslim who has a gray hair in Islam, a good deed is recorded for him because of it, and he will be elevated in rank or a sin will be removed from him because of it."  

قَالَ رَسُولُ اللهِ ﷺ لَا تَنْتِفُوا الشَّيْبَ فَإِنَّهُ نُورُ الْمُسْلِمِ مَا مِنْ مُسْلِمٍ يَشِيبُ شَيْبَةً فِي الْإِسْلَامِ إِلَّا كُتِبَ لَهُبِهَا حَسَنَةٌ وَرُفِعَ بِهَا دَرَجَةً أَوْ حُطَّ عَنْهُ بِهَا خَطِيئَةٌ  

That the Messenger of Allah ﷺ said: "Whoever develops some gray hair in the cause of Allah, it shall be a light for him in the Day of Judgement. (Using translation from Tirmidhī 1635)   

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ شَابَ شَيْبَةً فِي الْإِسْلَامِ كَانَتْ لَهُ نُورًا يَوْمَ الْقِيَامَةِ»  

" لَا تَنْتِفُوا الشَّيْبَ فَإِنَّهُ نُورُ الْمُسْلِم، مَا مِنْ مُسْلِمٍ يَشِيبُ شَيْبَةً فِى الإِسْلَامِ إِلَّا كَتَبَ الله لَهُ بِهَا حَسَنَةً، وَرَفَعَهُ بِهَا دَرَجَةً وَحَطَّ عَنْهُ بِهَا خَطِيئَةً".
