It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Major sins are these: associating partners with Allah Almighty, disobedience to parents, killing a soul, and false oath. Imam Shu’bah was in doubt.

Sayyiduna Salamah bin Qais Ashja'i (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said during the Farewell Pilgrimage: Beware! There are only four things: That you do not associate partners with Allah, do not kill a soul which Allah has forbidden except with due right, do not commit adultery, and do not steal. Then Sayyiduna Salamah (may Allah be pleased with him) said: I am the most eager regarding them, because I myself heard them from the Messenger of Allah (peace and blessings be upon him).

Narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Beware of oppression! For oppression will be (many) darknesses on the Day of Resurrection. Avoid foul speech, for indeed Allah Almighty does not like abusive and obscene language. And beware of intense love for wealth! For this very thing destroyed those before you; it commanded them to sever ties of kinship, so they severed them; it incited them to miserliness, so they became miserly; and it commanded them to commit evil, so they committed evil. A man stood up and said: Which Islam is best? The Prophet (peace and blessings be upon him) replied: That other Muslims are safe from your tongue and your hand.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Abusing one’s parents is among the major sins. The people asked: How can a man abuse his own parents? He (peace and blessings be upon him) replied: He abuses someone’s father, so that person abuses his father in return; he abuses someone’s mother, so that person abuses his mother in return. Sufyan narrated this hadith as marfu‘ and Mis‘ar narrated it as mawquf.

(Second chain) The Messenger of Allah, peace and blessings be upon him, said: Indeed, disobedience to parents is the greatest of the major sins. Someone asked: What is meant by disobedience to parents? He, peace and blessings be upon him, said: A man abuses another man, and in retaliation, the latter abuses his father; and he insults his mother, and in response, the latter insults his mother.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Whoever abuses his father is accursed, and whoever speaks ill of his mother, curse has been invoked upon him.

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: One who persists in drinking alcohol, one who is disobedient to his parents, and one who reminds others of his favors will not enter the pure garden, that is, Paradise.

Sayyiduna Abu Darda (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: The one who is disobedient to parents, the one who habitually drinks alcohol, and the one who denies destiny will not enter Paradise.

It is narrated from Sayyiduna Mu’adh bin Anas al-Juhani (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Indeed, there are some servants of Allah Almighty whom Allah will neither speak to on the Day of Resurrection, nor purify them, nor look at them. Someone asked: O Messenger of Allah! Who are these people? He (peace and blessings be upon him) said: The one who disassociates himself from his parents, shows indifference towards them, the one who disassociates himself from his children, and the person upon whom a people have bestowed a favor, but he is ungrateful for their favor and disassociates himself from them.

It is narrated from Sayyiduna Saeed bin Zaid (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The greatest injustice is that a person violates his brother’s honor without any right, and indeed, maintaining ties of kinship is a branch of the Most Merciful; whoever severs it, Allah Almighty will make Paradise forbidden for him.
