Sign of the Day of Judgment: Family ties will be broken and neighborliness will deteriorate
عن عبد الله بن عمرو رضى الله عنه عن النبى صلى الله عليه وسلم قال : لا تقوم الساعة حتى يظهر الفحش والتفحش وقطيعة الأرحام وسوء الجوار
It is narrated from Hazrat Abdullah bin Amr (may Allah be pleased with them) that the Prophet Muhammad (peace be upon him and his family) said: "The Day of Judgment will not come until immorality spreads widely, severing of kinship becomes common, and bad neighborliness prevails."
Reference: Ahmad (263/2) Hakim (559/4) Abdul Razzaq (404/11) Majma' al-Zawa'id (632/7) Bazzar (3410)
وعن ابن مسعود رضى الله عنه عن النبى صلى الله عليه وسلم قال : إن بين يدي الساعة فشو التجارة وقطع الأرحام وشهادة الزور وكتمان شهادة الحق وظهور القلم
It is narrated from Hazrat Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: "Before the Day of Judgment, trade will become widespread, false testimony, concealment of truth, and excessive writing will become common, and kinship ties will be broken."

Benefits
(1) The breaking of kinship ties and severing of family relations, along with bad neighborliness, is a sign of the Day of Judgment, the manifestation of which has somewhat appeared.
(2) The Prophet Muhammad (peace be upon him) gave this warning for those who break kinship ties:
ولا يدخل الجنة قاطع رحم
"Whoever severs kinship will never enter Paradise."
(3) Many people, blinded by the glitter of wealth and riches, forget their poor relatives and seek new relatives, whereas Islam came to eliminate such discrimination, and in the eyes of Islam, poor relatives are more deserving of interaction and assistance to the best of one's ability.
(4) In the present era, many neighbors can be found who do not care at all about the joys and sorrows of others. Listening to obscene songs at high volume and not stopping even after being asked is a minor example of this.
(5) It is possible that near the Day of Judgment, the mentioned signs will go far beyond the current state.
(6) We should avoid being included in the list of such bad people through our actions and behavior and should exhibit good manners and qualities.
