Narrated by 'Abdur-Rahman b. Abu Bakra
It is narrated on the authority of 'Abdur-Rahman b. Abu Bakra that his father said: We were in the company of the Messenger of Allah (may peace be upon him) that he observed: Should I not inform you about the most grievous of the grave sins? (The Holy Prophet) repeated it three times, and then said: Associating anyone with Allah, disobedience to parents, false testimony or false utterance. The Holy Prophet was reclining, then he sat up, and he repeated it so many times that we wished that he should become silent.
Narrated by Anas

Narrated by Ubaidullah b. Abu Bakr
Ubaidullah b. Abu Bakr said: I heard Anas b. Malik saying: The Messenger of Allah (may peace be upon him) talked about the major sins, or he was asked about the major sins. Upon this he observed: Associating anyone with Allah, killing of a person, disobedience to parents. He (the Holy Prophet further) said: Should I not inform you about the gravest of the major sins, and (in this connection) observed: False utterance or false testimony. Shu'ba said: It was most probably "false testimony".
Narrated by Abu Huraira
It is reported on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) observed: Avoid the seven noxious things. It was said (by the hearers): What are they, Messenger of Allah? He (the Holy Prophet) replied: Associating anything with Allah, magic, killing of one whom God has declared inviolate without a just cause, consuming the property of an orphan, and consuming of usury, turning back when the army advances, and slandering chaste women who are believers, but unwary.
Narrated by 'Abdullah b. Amr b. al-'As
It is narrated on the authority of 'Abdullah b. Amr b. al-'As that the Messenger of Allah (may peace be upon him) observed: Abusing one's parents is one of the major sins. They (the hearers) said: Messenger of Allah, does a man abuse his parents too? He (the Holy Prophet) replied: Yes, one abuses the father of another man, who in turn abuses his father. One abuses his mother and he in turn abuses his (the formers) mother.
