The Messenger of Allah ﷺ said, "The lifespans of my nation range between sixty and seventy years, and few are those who exceed that."
أن رسول الله ﷺ قال: أعمار أمتي ما بين الستين إلى السبعين، وأقلهم من يجوز ذلك.
Tirmidhi (3550), Ibn Majah (4236), Ibn Hibban (2980), and Hakim (2/427) all narrated it, all of them through the hadith of Muhammad bin Amr, from Abu Salama, from Abu Hurairah, who mentioned it. Its chain is hasan because of Muhammad bin Amr, who is Ibn Alqama Laythi, for his hadith is hasan.Tirmidhi said, "This is a hasan gharib hadith through the hadith of Muhammad bin Amr from Abu Salama, from Abu Hurairah, from the Prophet ﷺ. We do not know it except through this route, though it has been narrated from Abu Hurairah through a route other than this one."
