Speaking in Persian or other languages and Allah’s statement on language diversity

Narrated Jabir bin Abdullah (may Allah be pleased with him): I once said, "O Messenger of Allah! We have slaughtered a small goat and ground a sa’ of barley flour, so please come with a few of your companions (may Allah be pleased with them)." The Prophet (peace and blessings of Allah be upon him) then called out loudly, "O people of the Trench! Jabir (may Allah be pleased with him) has prepared some food for you, so come quickly." (The word "Suran" is Persian; the chapter heading is derived from here.)

Lady Umm Khalid bint Khalid bin Sa'id (may Allah be pleased with her) says: I went with my father to the Messenger of Allah (peace and blessings of Allah be upon him), and at that time I was wearing a yellow (colored) shirt. The Messenger of Allah (peace and blessings of Allah be upon him) said: "Sanah." And this is a word in the Abyssinian language, which means "good" (i.e., it is good). Umm Khalid (may Allah be pleased with her) says: Then I began to play with the seal of Prophethood, so my father scolded me, but the Messenger of Allah (peace and blessings of Allah be upon him) said: "Leave her." After that, the Messenger of Allah (peace and blessings of Allah be upon him) (prayed for my long life, that is) said: "Wear it out and tear it, then wear it out and tear it, then wear it out and tear it."
