Sayyidah Aishah (may Allah be pleased with her) said: I did not see the Prophet (peace and blessings be upon him) (regularly) offering the voluntary Duha prayer, but I do offer it (regularly).
(b) In the narration of Ma'mar there is the addition: People have not introduced anything dearer to me than it.
(Note) By the words of Sayyidah Aishah (may Allah be pleased with her) 'inni la-usabbihuha' is meant: I persist in it; and by 'wa ma ahdatha al-nasu shay'an' she meant persisting in it.
