"There is no sin more worthy of Allah hastening the punishment upon its practitioner in the world – along with what is in store for him in the Hereafter – than tyranny and severing the ties of kinship.” (Sahih)  

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 قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
