Ata said concerning the idle oath (laghw) that Sayyidah Aishah (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) said: "It is a man's talk in his house: 'Kalla wallahi' (Certainly not, by Allah) and 'Bala wallahi' (Yes indeed, by Allah)." That is, he swears out of habit.
Abu Dawud said: Dawud bin Abi al-Furat narrated this hadith from Ibrahim al-Sa'igh, from Ata, from Aishah (may Allah be pleased with her) as mawquf; and al-Zuhri, Abd al-Malik and Malik bin Mighwal all narrated it from Ata, from Aishah (may Allah be pleased with her), as mawquf too. The Shaykh said: Likewise Amr bin Dinar, Ibn Jurayj and Hisham bin Hassan narrated it from Ata, from Aishah (may Allah be pleased with her), as mawquf.
