Anas bin Malik narrated the Messenger of Allah ﷺ said:
“This is the son of Adam, and this is his life span at his neck,’ then he spread his hand in front of him and said: ‘And there is his hope.”

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا النَّضْرُ بْنُ شُمَيْلٍ، أَنْبَأَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ : " هَذَا ابْنُ آدَمَ وَهَذَا أَجَلُهُ عِنْدَ قَفَاهُ " . وَبَسَطَ يَدَهُ أَمَامَهُ ثُمَّ قَالَ : " وَثَمَّ أَمَلُهُ " .
