“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.” (Using translation from Ibn Mājah 4211)
قَالَ رَسُولُ اللهِ ﷺ مَا مِنْ ذَنْبٍ أَحْرَى أَنْ يُعَجِّلَ اللهُ الْعُقُوبَةَ لِصَاحِبِهِ فِي الدُّنْيَا مَعَ مَا يَدَّخِرُ لَهُ فِي الْآخِرَةِ مِنَ الْبَغْيِ وَقَطِيعَةِ الرَّحِمِ
