quran:57:7 –

Believe in Allah and His Messenger and spend out of that in which He has made you successors. For those who have believed among you and spent, there will be a great reward.  

Believe, adhere to belief, in God and His Messenger, and expend, in the way of God, out of that over which He has made you successors, out of the wealth of those mentioned ˹whom you have succeeded˺, for you will be succeeded in this ˹wealth˺ by those who will come after you: this was revealed at the time of the ‘hardship’ campaign, the campaign of Tabūk. For those of you who believe and expend — an allusion to ‘Uthmān ˹b. ‘Affān˺, may God be pleased with him — will have a great reward.
القرآن:٥٧:٧ –

آمِنُوا بِاللَّهِ وَرَسُولِهِ وَأَنْفِقُوا مِمَّا جَعَلَكُمْ مُسْتَخْلَفِينَ فِيهِ ۖ فَالَّذِينَ آمَنُوا مِنْكُمْ وَأَنْفَقُوا لَهُمْ أَجْرٌ كَبِيرٌ  

{آمنوا} داوموا على الإيمان {بالله ورسوله وأنفقوا} في سبيل الله {مما جعلكم مستخلفين فيه} من مال من تقدمكم وسيخلفكم فيه من بعدكم، نزل في غزوة العسرة وهي غزوة تبوك {فالذين آمنوا منكم وأنفقوا} إشارة إلى عثمان ؓ {لهم أجر كبير}.
