Shuraih bin Hani (May Allah be pleased with him) reported:
I asked 'Aishah (may Allah be pleased with her): "What was the first thing which the Prophet ﷺ would do when he entered his house?" She replied: "He would use Miswak (tooth-stick)."
[Muslim].
وعن شريح بن هانئ قال: قلت لعائشة، رضي الله عنها: بأي شيء كان يبدأ النبي ﷺ إذا دخل بيته. قالت: بالسواك. ((رواه مسلم)).
