عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَكْثَرُ مَا كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يحلف: «لَا ومقلب الْقُلُوب» . رَوَاهُ البُخَارِيّ

‘A’isha said that the verse, "God will not take you to account for what is futile in your oaths” (Al-Qu’ran 2:225; 5:89) was sent down about such phrases as "No, by God,” and "Yes, by God.” Bukhari transmitted it. Sharh as-sunna has the wording of al-Masabih, saying that some transmitters traced it back to the Prophet on ‘A’isha’s authority.
