'Umar bin al-Khattab reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Allah, the Great and Majestic, forbids you to swear by your fathers. Umar said: By Allah. I have never sworn (by my father) since I heard Allah's Messenger ( صلی اللہ علیہ وسلم ) forbidding it mentioning them "on my behalf" nor on behalf of someone else.

This hadith has been transmitted on the authority of Zuhri except that in the hadith narrated on the authority of Uqail the words are: "I did not take oath by (anyone else except Allah) since I heard Allah's Messenger forbidding it, nor did I speak in such terms," and the narrator did not say, "on my own behalf or on behalf of someone else".

Salim reported on the authority of his father that Allah's Apostle ( صلی اللہ علیہ وسلم ) heard 'Umar while he was taking oath by his father. The rest of the hadith is the same.

'Abdullah (b. Umar) reported that Allah's Messenger ( صلی اللہ علیہ وسلم ) found, Umar bin al-Khattab amongst the riders and he was taking oath by his father Allah's Messenger ( صلی اللہ علیہ وسلم ) called them (saying): Our Allah, the Exalted and Majestic, has forbidden that you take oath by your father. He who has to take an oath, he must take it by Allah or keep quiet.

This hadith is narrated on the authority of Ibn 'Umar (RA) through another chain of transmitters.

Ibn 'Umar heard Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: He who has to take an oath, he must not take oath but by Allah. The Quraish used to take oath by their fathers. So he (the Holy Prophet) said: Do not take oath by your fathers.

Abu Hurairah (RA) reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: He who takes an oath in the course of which he says: By Lat (and al-'Uzza), he should say: There is no god but Allah; and that if anyone says to his friend: "Come and I will gamble with you," he should pay sadaqa.

This hadith has been narrated on the authority of Zuhri.

Abdul Rahman bin ahadeeth reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Do not swear by idols, nor by your fathers.

Abu Musa al-Ash'ari reported: I came to Allah's Apostle ( صلی اللہ علیہ وسلم ) along with a group of Ash'arites requesting to give us a mount. He (the Holy Prophet) said: By Allah, I cannot provide you with a mount, and there is nothing with me which I should give you as a ride. He (the narrator) said: We stayed there as long as Allah willed. Then there were brought to him (to the Holy Prophet) camels. He (the Holy Prophet) then ordered to give us three white humped camels, We started and said (or some of us said to the others): Allah will not bless us. We came to Allah's Messenger ( صلی اللہ علیہ وسلم ) begging him to provide us with riding camels. He swore that he could not provide us with a mount, but later on he provided us with that. They (some of the Prophet's Companions) came and informed him about this (rankling of theirs), whereupon he said: It was not I who provided you with a mount, but Allah has provided you with that. So far as I am concerned, by Allah, if He so wills, I would not swear, but if, later on, I would see better than it, I (would break the vow) and expiate it and do that which is better.
