divine provision and trust in Allah

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا ضَرَبْتُمْ فِى سَبِيلِ ٱللَّهِ فَتَبَيَّنُوا۟ وَلَا تَقُولُوا۟ لِمَنْ أَلْقَىٰٓ إِلَيْكُمُ ٱلسَّلَـٰمَ لَسْتَ مُؤْمِنًا تَبْتَغُونَ عَرَضَ ٱلْحَيَوٰةِ ٱلدُّنْيَا فَعِندَ ٱللَّهِ مَغَانِمُ كَثِيرَةٌ ۚ كَذَٰلِكَ كُنتُم مِّن قَبْلُ فَمَنَّ ٱللَّهُ عَلَيْكُمْ فَتَبَيَّنُوٓا۟ ۚ إِنَّ ٱللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا

O you who have believed, when you go forth [to fight] in the cause of Allāh, investigate; and do not say to one who gives you [a greeting of] peace, "You are not a believer," aspiring for the goods of worldly life; for with Allāh are many acquisitions. You [yourselves] were like that before; then Allāh conferred His favor [i.e., guidance] upon you, so investigate. Indeed Allāh is ever, of what you do, Aware.

وَإِذَا رَأَوْا۟ تِجَـٰرَةً أَوْ لَهْوًا ٱنفَضُّوٓا۟ إِلَيْهَا وَتَرَكُوكَ قَآئِمًا ۚ قُلْ مَا عِندَ ٱللَّهِ خَيْرٌ مِّنَ ٱللَّهْوِ وَمِنَ ٱلتِّجَـٰرَةِ ۚ وَٱللَّهُ خَيْرُ ٱلرَّٰزِقِينَ

But [on one occasion] when they saw a transaction or a diversion, [O Muḥammad], they rushed to it and left you standing. Say, "What is with Allāh is better than diversion and than a transaction, and Allāh is the best of providers."
