What does Middle Prayer mean?

Answer 1

The middle prayer is salat Al Asr

عَنْ يَحْيَى، سَمِعَ عَلِيًّا، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَ الأَحْزَابِ وَهُوَ قَاعِدٌ عَلَى فُرْضَةٍ مِنْ فُرَضِ الْخَنْدَقِ ‏ "‏ شَغَلُونَا عَنِ الصَّلاَةِ الْوُسْطَى حَتَّى غَرَبَتِ الشَّمْسُ مَلأَ اللَّهُ قُبُورَهُمْ وَبُيُوتَهُمْ - أَوْ قَالَ قُبُورَهُمْ وَبُطُونَهُمْ - نَارًا ‏"‏ ‏.‏

Yahya heard 'Ali saying that the Messenger of Allah (ﷺ) said on the day (of the Battle) of Ahzab, while sitting in one of the openings of the ditch: They (the enemies) have diverted us from the middle prayer till the sun set. May Allah fill their graves and their houses with fire, or their graves and stomachs with fire.
