Surah Hud was revealed in Makkah
Surah Hud made the Prophet’s Hair turn Gray
Abu `Isa At-Tirmidhi recorded from Ibn `Abbas that Abu Bakr said, “O Messenger of Allah, verily your hair has turned gray.” The Prophet replied,
شَيَّبَتْنِي هُودٌ وَالْوَاقِعَةُ
وَالْمُرْسَلَاتُ وَعَمَّ يَتَسَاءَلُونَ
وَإِذَا الشَّمْسُ كُوِّرَت
Surahs Hud, Al-Waqi`ah, Al-Mursalat, `Amma Yatasa’lun ﴿An-Naba’﴾ and Idhash-Shamsu Kuwwirat ﴿At-Takwir﴾ have turned my hair gray
In another narration he said,
هُودٌ وَأَخَوَاتُهَا
Surah Hud and its sisters…
بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ
In the Name of Allah, the Most Gracious, the Most Merciful.
