The Worst Deed in the Eyes of Allah

A man approached the Holy Prophet (s.a.w.s.) and enquired, "What is the worst deed in the eyes of Allah?"

The Holy Prophet (s.a.w.s.) replied,
"To attribute partners to Allah."
The man then asked, "After this which is the worst sin?"

The Holy Prophet (s.a.w.s.) said:
"To sever relations".

After this the same person asked, "After this which is the worst sin?"

The Holy Prophet (s.a.w.s.) replied:
"To enjoin the evil and to forbid the good (deeds)." 
(Al Kafi)

Goodness in Return of Ill-Treatment

A man complained to Imam Ja'far as-Sadiq (a.s.) about his relatives. Imam (a.s.) said, 
"Swallow your anger and behave nicely with your relatives."

The man said, "My relatives give me all sorts of troubles and there is hardly any cruelty they have not committed upon me." The Imam (a.s.) told him, 
"Do you also want to cut off relation with them? If you also become like them, then Allah will never have mercy for you."

Allama Majlisi (r.a.) says, "If one behaves kindly to the relatives who are bad, they would at one time or the other regret their behaviour. Then the Mercy of Allah will be upon both of them. If the ill-behaved relatives do not rectify their ways then at least the Mercy of Allah will be upon the one who continues kindness to them (the relatives).

It is very clear to us that we must not sever relations even with those relatives who are unkind to us and who want to cut off the relationships.

The Holy Prophet (s.a.w.s.) says:
"Do not sever relation with your kindered even if they cut off relations with you." 
(Al Kafi)

Imam Muhammad al-Baqir (a.s.) states:
"There are three sins whose punishment has to be borne in this world itself:-
The first is injustice, the second is breaking of relationships and the third is false oath." 
(Al Kafi)

Life is Shortened

Hazrat Ali (a.s.) says in one of his sermons: -
"I seek refuge from the sins which cause the hastening of death."

Someone asked him, "Maula, Is there any sin by which the death is hastened?" He replied, 
"Yes, the breaking up of the family ties."

Families who live with co-operation and care for each other are given increase in sustenance by Allah and those who remain divided and are aloof from each other, Allah removes the bounty from their sustenance and their lifespan shortens even if they are all pious (in other respects).

Death Due to Qat-e-Rahmi

A companion of Imam Ja'far as-Sadiq (a.s.) complained about the ill-treatment given to him by his relatives, 
"My own brother as well as my paternal cousins are harassing me. They have snatched the house that rightfully belonged to me and have given me only a room to live in. If I complain to the government, I shall be able to recover all my property.

Imam (a.s.) said, 
"Be patient, everything will be alright."

The man returned satisfied. In the year 131 A.H. there was a terrible plague. All the relatives of the man perished. Thereafter when he arrived before Imam Ja'far as-Sadiq (a.s.), he (Imam a.s.) asked, 
"How are your relatives?"

The man said, "By Allah all of them are dead." The Imam (a.s.) said, 
"Their deaths have been due to their ill-treatment and Qat-e-Rahmi of relatives like you, not recognizing your right and cutting off relationships."

Bereft of Divine Mercy

Imam Ja'far as-Sadiq (a.s.) relates from the Holy Prophet (s.a.w.s.) that he said:
"When people claim to possess knowledge but do not act upon it, when they claim to profess love but harbour malice in their hearts and sever relations, in such a condition Allah removes mercy from them and makes them undiscerning to logic. 
(Behaarul Anwaar)

The Holy Prophet (s.a.w.s.) says: 
"Among the various sins, injustice and cutting off relationships are such that one who commits these is punished in this world itself. Apart from this the punishment for these sinners has already been prepared in the Hereafter." 
(Mustadrak)

At another occasion the Holy Prophet (s.a.w.s.) has informed:
"One who severs relationships will not enter Heaven."

Jabir Ibne Abdullah Ansari (r.a.) has related from Imam Muhammad al-Baqir (a.s.) that he quotes the Holy Prophet (s.a.w.s.) as follows:
"Jibraeel (a.s.) has informed me that even at a distance of a thousand years man will be able to smell the fragrance of Heaven , but one who disobeys his parents, the one who breaks ties with the kith and kin, or the aged adulterer will not be able to smell it. In fact, the fragrance of Paradise will be felt even at a distance of two thousand years, but not by those who disobey their parents and those who break ties with the relatives."

The exalted Prophet of Islam (s.a.w.s.) has also informed that the invocation of the person who breaks family ties shall not be answered. "In the chapter on the merits of Shab-e-Qadr the Prophet (s.a.w.s.) has stated that in the night of Qadr Allah forgives the sins of all the people except of those who drink wine, who disobey their parents, and those who break ties with the relatives or harbour enmity towards the believers."
