“Abu Bakr [may Allah be pleased with him] said: ‘O Messenger of Allah! You have become gray.’ He said: ‘I have gone gray from (Surat) Hud, Al-Waqiʿah, Al-Mursalat and ʿAmma Yatasa'alun and Idhash-Shamsu Kuwwirat.’” (Using translation from Tirmidhī 3297)
أَبُو بَكْرٍ الصِّدِّيقُ لِرَسُولِ اللَّهِ ﷺ أَرَاكَ قَدْ شِبْتَ قَالَ «شَيَّبَتْنِي هُودٌ وَالْوَاقِعَةُ وَعَمَّ يَتَسَاءَلُونَ وَإِذَا الشَّمْسُ كُوِّرَتْ»
