Ka'b bin Malik (May Allah be pleased with him) said in his long story about his repentance:
The Prophet ﷺ was sitting among the people in Tabuk. He ﷺ said, "What happened to Ka'b bin Malik?" A person from the tribe of Banu Salamah said: "O Messenger of Allah! the embellishment of his cloak and an appreciation of his sides have allured him, and he was thus detained." Mu'adh bin Jabal (May Allah be pleased with him) said: "Woe be upon you! You have passed indecent remarks. O Messenger of Allah! by Allah, we know nothing about him but good." The Messenger of Allah ﷺ remained silent.

[Al-Bukhari and Muslim].

وعن كعب بن مالك رضي الله عنه في حديثه الطويل في قصة توبته وقد سبق في بابه التوبة. قال: قال النبي ﷺ وهو جالس في القوم بتبوك: "ما فعل كعب مالك؟ فقال رجل من بني سلمة: يا رسول الله حبسه برداه، والنظر في عطفيه فقال معاذ بن جبل رضي الله عنه بئس ما قلت والله يا رسول الله ما علمنا عليه إلا خيرًا، فسكت رسول الله ﷺ" ((متفق عليه)).
