Narrated Jabir bin 'Abdullah: that the Messenger of Allah ﷺ said: "The Salam is before talking". With this chain it has been reported that the Prophet ﷺ said: "Do not invite anyone to the food until the Salam is given".
The Prophet Muhammad ﷺ taught us that by being polite and respectful towards others, we can create strong bonds between ourselves and those around us. He also taught us that by showing kindness towards others, even if it’s something as simple as saying “As-salamu alaykum” when meeting someone new, it can help build trust between people and create an atmosphere of peace and harmony.
