Jami` at-Tirmidhi Book 17, Hadith 6
That the Messenger of Allah (ﷺ) said: "The Muslim is the brother of the Muslim, he doesn't oppress him and doesn't put him into ruin, and whoever is concerned for the needs of his brother, Allah is concerned for his needs, and whoever relieves a Muslim of a burden, Allah will relieve him of a burden from the burdens of the Day of Judgement and whoever covers (the faults of) a Muslim, Allah will cover (his faults) on the Day of Judgement."
"It has been narrated to me from Abu Salih, from Abu Hurairah, from the Prophet (ﷺ)," and it is similar. (Another chain) for this Hadith.
That the Prophet (ﷺ) said to Ma'iz bin Malik: "Is what has reached me about you true?" He said: "What has reached you about me?" He said: "It has reached me that you had relations with the slave-maid of the family of so-and-so" He said: "Yes." So he testified four times, and he gave the order that he be stoned.
