Sunan an-Nasa'i 1459
It was narrated that Abu Bakrah said:
"The Messenger of Allah (ﷺ) said: 'The sun and moon are two signs of Allah (SWT), the Most High, and they do not become eclipsed for death or birth of anyone, rather Allah (SWT), the Mighty and Sublime, strikes fear into His slaves through them.'"
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏
"‏‏ إِنَّ الشَّمْسَ وَالْقَمَرَ آيَتَانِ مِنْ آيَاتِ اللَّهِ تَعَالَى لاَ يَنْكَسِفَانِ لِمَوْتِ أَحَدٍ وَلاَ لِحَيَاتِهِ وَلَكِنَّ اللَّهَ عَزَّ وَجَلَّ يُخَوِّفُ بِهِمَا عِبَادَهُ ‏‏"‏‏ ‏‏.‏‏
