Reading from the author's text with commentary and collation of manuscripts: "In summary: using a foreign word after a foreign word is a close matter

The reader: "In summary, using a foreign word after a foreign word is a close matter, and they mostly do this either because the person being addressed is a non-Arab or because they have become accustomed to foreign words, intending to make understanding easier for him, just as the Prophet (peace and blessings be upon him) said to Umm Khalid"

The Shaykh : The apparent meaning is making understanding easier, with the kasrah, meaning that they make his understanding easier, yes.
The reader: "intending to make understanding easier for him, just as the Prophet (peace and blessings be upon him) said to Umm Khalid, the daughter of Khalid ibn Sa'id ibn al-As, and she was a small girl who had been born in the land of Abyssinia when her father emigrated, so the Prophet (peace and blessings be upon him) clothed her in a khimayisah and said

Narrated Um Khalid bint Khalid: Some clothes were presented to Allah's Messenger (ﷺ) as a gift and there was a black Khamisa with it. The Prophet asked (his companions), "To whom do you suggest we give this Khamisa?" The people kept quiet. Then he said, "Bring me Um Khalid," So I was brought to him and he dressed me with it with his own hands and said twice, "May you live so long that you will wear out many garments." He then started looking at the embroidery of that Khamisa and said, "O Um Khalid! This is Sana!" (Sana in Ethiopian language means beautiful.) 'Is-haq, a sub-narrator, said: A woman of my family had told me that she had seen the Khamisa worn by Um Khalid.

يا أم خالد هذا سنا والسنا بلغة الحبشة الحسن

Sahih al-Bukhari 5845

and it was narrated from Abu Hurayrah (may Allah be pleased with him) that he said to someone whose stomach was hurting him: 'Ashkam bi-dard,' and some of them narrate it as marfu' (traced to the Prophet), but it is not authentic"
He said: "Shkam means the stomach in Persian, and I did not find the meaning of bi-dard, and perhaps it means pain or something similar"

The Shaykh : This is 'Abdullah teaching us.
The student: Shkam bi-dard.

The Shaykh : Ah?
The student: Shkam bi-dard, not bi-dard.

The Shaykh : Bi-dard.
The student: Bi-dard, yes.

The Shaykh : It is like that with you.
The student: It is not said like that; shkam means stomach and bi-dard means pain.

The Shaykh : Pain.
The student: Yes

The Shaykh : Even what we have now, ashkam bi-dard, is like that with us.
The student: Bi-dard; dard is known to mean pain.

The Shaykh : Yes.
The student: ...

The Shaykh : Ashkam bi-dard, where is it? It is not there.
The student: Shkam bi-dard.

The Shaykh : Meaning the hamzah is extra.
The student: Extra, yes.

The Shaykh : Yes, perhaps it was not extra at that time.
