Hadith: The Rahim (kinship ties) is hanging on to the Hujzah of the Most Merciful; He maintains ties with whoever maintains it (the Rahim) and severs ties with whoever severs it

عن ابن عباس رضي الله عنهما مرفوعاً: «إنَّ الرَّحِمَ شِجْنَةٌ آخذةٌ بحُجْزَةِ الرَّحمنِ، يَصِلُ مَن وَصَلَها، ويقطعُ مَن قَطَعَها».
[صحيح] - [رواه أحمد]

Ibn ‘Abbās (may Allah be pleased with him) reported in the Prophet (may Allah's peace and blessings be upon him) said: "The Rahim (kinship ties) is hanging on to the Hujzah of The Most Merciful; He maintains ties with whoever maintains it (the Rahim) and severs ties with whoever severs it."
[Authentic hadith] - [Narrated by Ahmad]

Explanation

The "Rahim" (kinship ties) is related to Allah, Glorified and Exalted. Its name is derived from His name Ar-Rahmān (the Most Merciful). This Hadīth, in general, is one of the Hadīths that talk about Allah's attributes. Scholars stated that such Hadīths should be received as they are reported, and they refuted the claim of those who denied its apparent meaning. The "Hujzah" (literally: a place where the lower garment is fastened) is from the attributes of Allah in which we have to believe without distorting or denying their meanings, without attempting to describe how or likening such attributes to the creatures. So, we believe that the "Rahim", which is the kinship ties, hangs on to it (the Hujzah) and that Allah, Glorified and Exalted, maintains ties with whoever maintains it, and severs ties with whoever severs it. Anyone Allah cuts off will be distanced with the enemy of Allah, the cursed Satan. Even if all the creatures wanted to maintain relations with him and benefit him, it would be of no avail to him.
