Riyad as-Salihin, 1524

Abu Bakrah (May Allah be pleased with him) said:

Delivering the sermon during the Farewell Pilgrimage on the day of Sacrifice at Mina, the Messenger of Allah (ﷺ) said, "Verily your blood, your property and your honour are as sacred and inviolable as the sanctity of this day of yours, in this month of yours and in this town of yours. Verily! I have conveyed this message to you." <b>[Al-Bukhari and Muslim]</b>

وعن أبي بكر رضي الله عنه أن رسول الله صلى الله عليه وسلم قال في خطبته يوم النحر بمنًى في حجة الوداع‏:‏ ‏"‏إن دماءكم، وأموالكم، وأعراضكم حرام عليكم كحرمة يومكم هذا، في شهركم هذا، في بلدكم هذا، ألا هل بلغت” ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

<b>Guidance from the Hadiths:</b><br> 1) The Hadith warns against backbiting, being one of the grave major sins, and one of the causes of destruction for its doer in the worldly life and the Hereafter.<br> 2) It is prohibited to speak about other Muslims in a way that they do not like, even if what is said is true about them, for it is considered backbiting. It is allowable under the Shariah in some cases only.<br> 3) The Muslim’s life, property, and honor are as inviolable in the sight of Allah as are the sacred town, the sacred month, and the sacred day.<br> 4) Belittling the value of the worldly life and everything in it if compared to the pleasure of Allah Almighty.<br> 5) Mentioning the punishment of backbiters on the Day of Judgment; they will torture themselves with their own hands because they allowed their fellow Muslims to be backbitten, so they will reap what they sowed.
