Ibn Sa'd meriwayatkan bahawa 'Aisyah, semoga Allah meridhainya, berkata bahawa seorang lelaki pernah berkata kepadanya, "Ceritakanlah kepada kami tentang Abu Bakar." Beliau berkata, "Seorang lelaki yang berkulit cerah, bertubuh kurus, pipinya cekung, dan sedikit membongkok; kainnya sentiasa melorot dari pinggangnya; wajahnya tirus, matanya cekung ke dalam, dahinya menonjol, dan belakang tangannya kurus tanpa daging. Inilah sifatnya." Beliau juga meriwayatkan bahawa 'Aisyah, semoga Allah meridhainya, berkata bahawa Abu Bakar biasa mewarnai [rambut dan janggutnya] dengan inai dan nila (katam).

Ibn Sacd narrated that cA’ishah, may Allah be pleased with her, said that a man said to her, ‘Describe Abu Bakr to us.’ She said, ‘A fair man, of slender build, thin cheeked and with a stoop; he could not keep his lower garment from slipping over his loins; gaunt-faced, eyes deep-set, with a prominent forehead, and the backs of his hands fleshless. This is his description.’ He narrated that cA’ishah, may Allah be pleased with her, said that Abu Bakr used to dye [his hair and beard] with henna and indigo (katam).

Beliau meriwayatkan bahawa Anas berkata: Rasulullah ﷺ tiba di Madinah dan tiada seorang pun daripada para sahabat baginda yang mempunyai rambut bercampur putih dan hitam melainkan Abu Bakar, maka beliau mewarnainya dengan inai dan katam {katam}.

He narrated that Anas said: The Messenger of Allah, may Allah bless him and grant him peace, went to Madinah and there was no-one among his companions having hair of mixed white and black except Abu Bakr, so he dyed it with henna and indigo {katam).
