Sahih al-Bukhari, 4438

Narrated Aisha:`Abdur-Rahman bin Abu Bakr entered upon the Prophet (ﷺ) while I was supporting the Prophet (ﷺ) on my chest. `AbdurRahman had a fresh Siwak then and he was cleaning his teeth with it. Allah's Messenger (ﷺ) looked at it, so I took the Siwak, cut it (chewed it with my teeth), shook it and made it soft (with water), and then gave it to the Prophet (ﷺ) who cleaned his teeth with it. I had never seen Allah's Messenger (ﷺ) cleaning his teeth in a better way. After finishing the brushing of his teeth, he lifted his hand or his finger and said thrice, "O Allah! Let me be with the highest companions," and then died. `Aisha used to say, "He died while his head was resting between my chest and chin

Rapporté par `Aisha : `Abdur-Rahman bin Abu Bakr entra auprès du Prophète (ﷺ) pendant que je soutenais le Prophète (ﷺ) contre ma poitrine. `Abdur-Rahman avait un siwak neuf et il se nettoyait les dents avec. Le Messager d’Allah (ﷺ) le regarda, alors je pris le siwak, je le mâchai pour l’assouplir, je le secouai et le mouillai, puis je le donnai au Prophète (ﷺ) qui se nettoya les dents avec. Je n’ai jamais vu le Messager d’Allah (ﷺ) se brosser les dents aussi soigneusement. Après avoir fini, il leva la main ou le doigt et dit trois fois : « Ô Allah ! Permets-moi d’être avec les plus hauts compagnons », puis il mourut. `Aisha disait : « Il est mort alors que sa tête reposait entre ma poitrine et mon menton. »
