Shortening and Combining Prayers in Travel for Work and the Distance for Shortening

The questioner:
We take the connected caller, Majid, and I hope the audio is coming through clearly. Please go ahead. Peace be upon you. And upon you be peace. My question is for Shaykh Salih (may Allah preserve him). I travel for work, which is one hundred and seventy kilometers. So, what is best? I would like to know if I should shorten and combine the prayers, or just shorten them at their prescribed times?

The Shaykh:
No, my brother, you do not shorten the prayer for seventy kilometers because it is less than the distance for shortening. The distance for shortening is eighty kilometers or more. Yes.

The presenter:
If he says, "Shaykh, it is one hundred and seventy."

The Shaykh:
No, he did not say one hundred and seventy. Is he present or not?

The presenter:
The connected caller. Okay. Thank you. If

The Shaykh:
If it is one hundred and seventy kilometers, then he may shorten and combine the prayers. But if it is only seventy kilometers, then he may not do so.
