Ibn Abbas (may Allah be pleased with him) narrates: Abu Bakr (may Allah be pleased with him) said, "O Messenger of Allah! You have grown old." The Prophet (peace and blessings be upon him) replied: "Surah Hud, Al-Waqi'ah, Al-Mursalat, 'Amma Yatasa'aloon, and Surah Ash-Shams have made me old." (Tirmidhi) And the hadith narrated from Abu Hurairah (may Allah be pleased with him): "He will not enter Hell." is mentioned in the chapter of Jihad. Its chain is weak, narrated by Tirmidhi.
