The meaning of the ornamentation of the Hereafter

We were told by Abdullah bin Hasan, the teacher, from Ahmad bin Ali al-Esbahani, from Ibrahim bin Muhammed al-Thaqafi, that he said: We were told by Abu’l-Hasan, Ali bin Muhammed, a teacher from the people of Ray, that he said: We were told by Mansur bin Abbas, and Hasan bin Ali bin Nadr, of Sa’eed bin Nadr, of Ja’far bin Muhammed, peace be upon them both, that he said: Property and children are the ornamentation of the life of this world, and eight rak’at from the (prayer of the) last (part of the) night and the Witr [1] is the ornamentation of the Hereafter, and it may be that Allah, Exalted and Glorious is He, gathers them to some people.
