spiritual preparation

بَلَىٰٓ ۚ إِن تَصْبِرُوا۟ وَتَتَّقُوا۟ وَيَأْتُوكُم مِّن فَوْرِهِمْ هَـٰذَا يُمْدِدْكُمْ رَبُّكُم بِخَمْسَةِ ءَالَـٰفٍ مِّنَ ٱلْمَلَـٰٓئِكَةِ مُسَوِّمِينَ

Yes, if you remain patient and conscious of Allāh and they [i.e., the enemy] come upon you [attacking] in rage, your Lord will reinforce you with five thousand angels having marks [of distinction]."

وَثِيَابَكَ فَطَهِّرْ

And your clothing purify.

أَلَمْ نَشْرَحْ لَكَ صَدْرَكَ

Did We not expand for you, [O Muḥammad], your breast?
