Sahih Muslim 2608 a
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.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، وَعُثْمَانُ بْنُ أَبِي شَيْبَةَ، - وَاللَّفْظُ لِقُتَيْبَةَ - قَالاَ حَدَّثَنَا جَرِيرٌ،
 عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ، عَنِ الْحَارِثِ بْنِ سُوَيْدٍ، عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ، قَالَ قَالَ
 رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا تَعُدُّونَ الرَّقُوبَ فِيكُمْ ‏"‏ ‏.‏ قَالَ قُلْنَا الَّذِي لاَ يُولَدُ
 لَهُ ‏.‏ قَالَ ‏"‏ لَيْسَ ذَاكَ بِالرَّقُوبِ وَلَكِنَّهُ الرَّجُلُ الَّذِي لَمْ يُقَدِّمْ مِنْ وَلَدِهِ شَيْئًا ‏"‏ ‏.‏ قَالَ ‏"‏ فَمَا
 تَعُدُّونَ الصُّرَعَةَ فِيكُمْ ‏"‏ ‏.‏ قَالَ قُلْنَا الَّذِي لاَ يَصْرَعُهُ الرِّجَالُ ‏.‏ قَالَ ‏"‏ لَيْسَ بِذَلِكَ وَلَكِنَّهُ
 الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ ‏"‏ ‏.‏
