37- وبه: عن عائشة أم المؤمنين أنها قالت: ما سبح رسول الله صلى الله عليه وسلم سبحة الضحى قط وإني لأستحبها، وإن كان رسول الله صلى الله عليه وسلم ليدع العمل وهو يحب أن يعمل به خشية أن يعمل به الناس فيفرض عليهم.
And with the same chain of narration, it is narrated from Umm al-Mu'minin Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) never performed the Duha prayer (regularly), and I consider this prayer to be recommended. The Messenger of Allah (peace and blessings be upon him), despite liking an action, would sometimes leave it out of fear that it might become obligatory upon people due to their continuous practice of it.
