”وَبَابَانِ يُعَجَّلاَنِ فِي الدُّنْيَا: الْبَغْيُ، وَقَطِيعَةُ الرَّحِمِ.“
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The punishment for two sins is hastened in this world as well: oppression and severing ties of kinship."
