It was narrated from Abu Bakrah that the Messenger of Allah ﷺ said:
“There is no sin more deserving that Allah hasten the punishment in this world, in addition to what is stored up for him in the Hereafter – than injustice and severing the ties of kinship.”

حَدَّثَنَا الْحُسَيْنُ بْنُ الْحَسَنِ الْمَرْوَزِيُّ، أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، وَابْنُ، عُلَيَّةَ عَنْ عُيَيْنَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، عَنْ أَبِي بَكْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ ﷺ ـ " مَا مِنْ ذَنْبٍ أَجْدَرُ أَنْ يُعَجِّلَ اللَّهُ لِصَاحِبِهِ الْعُقُوبَةَ فِي الدُّنْيَا مَعَ مَا يَدَّخِرُ لَهُ فِي الآخِرَةِ - مِنَ الْبَغْىِ وَقَطِيعَةِ الرَّحِمِ " .
