Once Allah's Messenger (ﷺ) passed by an Ansari (man) who was admonishing his brother regarding Haya'. On that Allah's Messenger (ﷺ) said, "Leave him as Haya' is a part of faith." (See Hadith 9)
Sahih al-Bukhari Book 2, Hadith 17
← Previous Hadith Allah's Messenger (ﷺ) said, "While I was sleeping I saw (in a dream) some people wearing shirts of which some were reaching up to the breasts only while others were even shorter than that. Umar bin Al-Khattab was shown wearing a shirt that he was dragging." The people asked, "How did you interpret it? (What is its interpretation) O Allah's Messenger (ﷺ)?" He (the Prophet (ﷺ) ) replied, "It is the Religion."

Sahih al-Bukhari Book 2, Hadith 16 Next Hadith → Allah's Messenger (ﷺ) said: "I have been ordered (by Allah) to fight against the people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Messenger (ﷺ), and offer the prayers perfectly and give the obligatory charity, so if they perform that, then they save their lives and property from me except for Islamic laws and then their reckoning (accounts) will be done by Allah."
