[Machine] We were with the Messenger of Allah ﷺ on the day of the trench, and we were occupied from performing prayers. So the Messenger of Allah ﷺ ordered Bilal to establish each prayer, and that was before the verse {So if you fear, then prayer on foot or riding} [Al-Baqarah 2:239] was revealed to him.
كُنَّا مَعَ رَسُولِ اللهِ ﷺ يَوْمَ الْخَنْدَقِ فَشُغِلْنَا عَنْ صَلَوَاتٍ فَأَمَرَ رَسُولُ اللهِ ﷺ بِلَالًا فَأَقَامَ لِكُلِّ صَلَاةٍ إِقَامَةً وَذَلِكَ قَبْلَ أَنْ يَنْزِلَ عَلَيْهِ {فَإِنْ خِفْتُمْ فَرِجَالًا أَوْ رُكْبَانًا} [البقرة 239]
