Ṣaḥīḥ Muslim 6641
لَيْسَ ذَاكَ بِالرَّقُوبِ وَلَكِنَّهُ الرَّجُلُ الَّذِي لَمْ يُقَدِّمْ مِنْ وَلَدِهِ شَيْئًا
laysa dhāka bi-ar-raqūbi walakinnah ar-rajulu adh-dhī lam yuqaddim min waladihi shayʾan

The full narration
Abdullah b. Mas'ud reported Allah's Messenger (ﷺ) as saying:Whom do you count as" Raqub" amongst you? They (his Companions) said: One who has no children (the children are born unto him but they do not survive). Thereupon he (the Holy Prophet) said: He is not a Raqub but Raqub is one who does not find his child as the forerunner (in Paradise). He then said: Whom do you count as a wrestler amongst you? We said: He who wrestles with persons. He said: No, it is not he but one who controls himself when in a fit of rage
