وَلِيَعْلَمَ الَّذِينَ نَافَقُوا وَقِيلَ لَهُمْ تَعَالَوْا قَاتِلُوا فِي سَبِيلِ اللَّهِ أَوِ ادْفَعُوا قَالُوا لَوْ نَعْلَمُ قِتَالًا لَّاتَّبَعْنَاكُمْ هُمْ لِلْكُفْرِ يَوْمَئِذٍ أَقْرَبُ مِنْهُمْ لِلْإِيمَانِ يَقُولُونَ بِأَفْوَاهِهِم مَّا لَيْسَ فِي قُلُوبِهِمْ وَاللَّهُ أَعْلَمُ بِمَا يَكْتُمُونَ ١٦٧

ادْفَعُوا id'faʿū · defend

And that He might make evident those who are hypocrites. For it was said to them, "Come, fight in the way of Allāh or [at least] defend." They said, "If we had known [there would be] battle, we would have followed you." They were nearer to disbelief that day than to faith, saying with their mouths what was not in their hearts. And Allāh is most knowing of what they conceal - (Surah Ali 'Imran, 3:167)

وَابْتَلُوا الْيَتَامَىٰ حَتَّىٰ إِذَا بَلَغُوا النِّكَاحَ فَإِنْ آنَسْتُم مِّنْهُمْ رُشْدًا فَادْفَعُوا إِلَيْهِمْ أَمْوَالَهُمْ وَلَا تَأْكُلُوهَا إِسْرَافًا وَبِدَارًا أَن يَكْبَرُوا وَمَن كَانَ غَنِيًّا فَلْيَسْتَعْفِفْ وَمَن كَانَ فَقِيرًا فَلْيَأْكُلْ بِالْمَعْرُوفِ فَإِذَا دَفَعْتُمْ إِلَيْهِمْ أَمْوَالَهُمْ فَأَشْهِدُوا عَلَيْهِمْ وَكَفَىٰ بِاللَّهِ حَسِيبًا ٦

فَادْفَعُوا fa-id'faʿū · then deliver

And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgement, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor - let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allāh as Accountant. (Surah An-Nisa, 4:6)

فَهَزَمُوهُم بِإِذْنِ اللَّهِ وَقَتَلَ دَاوُودُ جَالُوتَ وَآتَاهُ اللَّهُ الْمُلْكَ وَالْحِكْمَةَ وَعَلَّمَهُ مِمَّا يَشَاءُ وَلَوْلَا دَفْعُ اللَّهِ النَّاسَ بَعْضَهُم بِبَعْضٍ لَّفَسَدَتِ الْأَرْضُ وَلَٰكِنَّ اللَّهَ ذُو فَضْلٍ عَلَى الْعَالَمِينَ ٢٥١

دَفْعُ dafʿu · (for the) repelling

So they defeated them by permission of Allāh, and David killed Goliath, and Allāh gave him the kingship and wisdom [i.e., prophethood] and taught him from that which He willed. And if it were not for Allāh checking [some] people by means of others, the earth would have been corrupted, but Allāh is the possessor of bounty for the worlds. (Surah Al-Baqarah, 2:251)
