بسم الله الرحمن الرحيم
In surah Al-Anfāl verse ٢٥ on the mobile app from reciter Raad al-kurdi' recitation, on the last word العقاب the audio is cut short and faded off right before the last letter ب is pronounced, so it sounds like he says
شديد العقا... واذكروا
instead of the full pronunciation
وَٱعۡلَمُوۤا۟ أَنَّ ٱللَّهَ شَدِیدُ ٱلۡعِقَابِ (٢٥)...
....وَٱذۡكُرُوۤا۟ إِذۡ أَنتُمۡ قَلِیلࣱ مُّسۡتَضۡعَفُونَ فِی ٱلۡأَرۡضِ
(To the end of the ayah)
In summary the ب from the word العقاب in ayah ٢٥ was not pronounced or atleast not visible in the audio
والله أعلم واللهم هدانا
(BTW I use an android)
إن شاء الله let me know if I was mistaken.
