Hadith 1444
'Aishah (May Allah be pleased with her) reported:
وعن عائشة رضي الله عنها قالت: كان رسول الله صلى الله عليه وسلم يذكر الله تعالى على كل أحيانه. رواه مسلم.
The Messenger of Allah (ﷺ) used to remember Allah at all times. [Muslim].
In plain words
The Prophet kept Allah in his remembrance at all times. No state of life was treated as off-limits for remembering Allah.
