Narrated Abdullah ibn Abbas: The Prophet صلی اللہ علیہ وسلم said: If anyone takes a vow but does not name it, its atonement is the same as that for an oath, if anyone takes a vow to do an act of disobedience, its atonement is the same as that for an oath, if anyone takes a vow he is unable to fulfill, its atonement is the same as that for an oath, but if anyone takes a vow he is able to fulfill, he must do so. Abu Dawud said: This tradition has been transmitted by Waki and others on the authority of Abdullah bin Saeed bin Abi al-Hind, but they traced it no farther back than Ibn Abbas.

Narrated Uqbah bin Amir: The Messenger of Allah صلی اللہ علیہ وسلم as saying: The atonement for a vow is the same as for an oath. Abu Dawud said: This tradition has also been transmitted by Amr bin al-Harith from Kab bin Alqamah, from Ibn Shamasah on the authority of Uqbah.

A similar tradition has also been transmitted by Uqbah bin Amir from the Prophet صلی اللہ علیہ وسلم through a different chain of narrators.

Narrated Ibn Umar: That Umar said: Messenger of Allah, I took a vow in pre-Islamic times that I would stay in the sacred mosque (Masjid Haram) as a devotion (Itikaf). The Prophet صلی اللہ علیہ وسلم said: Fulfill your vow.
