Breaking the ties of kinship is a sin that the Muslim whose heart is filled with true guidance and the desire to obey Allah and earn His pleasure will never commit because it is one of the sins that Allah has said will bring punishment; indeed, it is one of the foremost sins for which Allah will punish the one who is guilty of them both in this world and the next, as is stated in the hadith: “There is no worse sin for which Allah will hasten the punishment of one who is guilty of it in this world – in addition to what awaits him in the Hereafter – than the breaking the ties of kinship and oppressing others.” (Ahmad)
Upholding the ties of kinship is counted as one of the major characteristics of this religion, along with pure monotheistic belief in Allah, establishing prayer, and adherence to truthfulness and chastity, which were being explained to those questioners for the very first time.
A Muslim’s kindness, respect, and good treatment are not limited just to his parents, spouse, and children, but extend to his relatives, all of whom he should treat well. In the Qur’an, the word used is arhaam (literally wombs), which refers to relatives to whom a person is linked by ties of blood, whether they are his heirs or not.
