Abu Bakra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "There is no wrong action which Allah is swifter to punish in this world - in addition to the punishment which He has stored up for the wrongdoer in the Next World - than cutting off ties of kinship and injustice."  

قَالَ رَسُولُ اللهِ ﷺ مَا مِنْ ذَنْبٍ أَحْرَى أَنْ يُعَجِّلَ اللَّهُ لِصَاحِبِهِ الْعُقُوبَةَ فِي الدُّنْيَا مَعَ مَا يَدَّخِرُ لَهُ فِي الْآخِرَةِ مِنْ قَطِيعَةِ الرَّحِمِ وَالْبَغْيِ
