IBNMAJAH 4211: from Abū Bakrah —
“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.”

ابن ماجة ٤٢١١: عن ابو بكره —
قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ ذَنْبٍ أَجْدَرُ أَنْ يُعَجِّلَ اللَّهُ لِصَاحِبِهِ الْعُقُوبَةَ فِي الدُّنْيَا مَعَ مَا يَدَّخِرُ لَهُ فِي الآخِرَةِ مِنَ الْبَغْىِ وَقَطِيعَةِ الرَّحِمِ
