NASAI-KUBRA 11763:
from ʿUbaydullāh b. Abū Bakr b. Anas from his grandfather Anas —
"This is the son of Adam, and this is his life-span." And he placed his hand at the (height of the) nape of his neck, then he extended it (higher) and said:" From there is what is hoped for, from there is what is hoped for." (Using translation from Tirmidhī 2334)
الكبرى للنسائي ١١٧٦٣:
عن عبيد الله بن ابو بكر بن انس عن جده انس —
قَالَ رَسُولُ اللهِ ﷺ «هَذَا ابْنُ آدَمَ وَهَذَا أَجْلُهُ» وَوَضَعَ يَدَهُ عِنْدَ قَفَاهُ ثُمَّ بَسَطَهَا فَقَالَ «وَثَمَّ أَمَلُهُ وَثَمَّ أَمَلُهُ»
