وَمَا لَكُمْ أَلَّا تُنفِقُوا فِي سَبِيلِ اللَّهِ وَلِلَّهِ مِيرَاثُ السَّمَاوَاتِ وَالْأَرْضِ لَا يَسْتَوِي مِنكُم مَّنْ أَنفَقَ مِن قَبْلِ الْفَتْحِ وَقَاتَلَ أُولَئِكَ أَعْظَمُ دَرَجَةً مِّنَ الَّذِينَ أَنفَقُوا مِن بَعْدُ وَقَاتَلُوا وَكُلًّا وَعَدَ اللَّهُ الْحُسْنَى وَاللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ
Why should you not spend in the way of Allah, when to Allah belongs the heritage of the heavens and the earth? Those of you who spent [their means] and fought before the victory are not equal [to others]. They are greater in rank than those who have spent and fought afterwards. Yet Allah has promised the best reward to each and Allah is well aware of what you do.
Agha Ali Puya Commentary
Commentary on Quran 57:10
[Pooya/Ali Commentary 57:10] For spending in the cause of Allah refer to the commentary of verse 7. Before the fall of Makka the Muslims were a very poor community, so those who spent in the cause of Allah in such days of distress are superior to those who spent after the removal of poverty when economic prosperity was achieved. It is a historical fact that the wealth of Khadijah Kubra inherited by Fatimah Zahra and her children was spent to feed not only the displaced muhajirs but also to finance the battles fought by the Holy Prophet to defend the small community of Muslims. As far as the fighting in the way of Allah is concerned none can be cited save Ali whose valour and courage won all the battles fought by the Holy Prophet. Refer to the commentary of Ali Imran: 13 and Anfal: 5 (Badr); Ali Imran: 121 to 168 and Anfal: 16 (Uhad); Bara-at: 25 to 27 (Hunayn) Baqarah: 214, 251 and Ahzab: 1 to 3, 9 to 27 (Khandaq) and Fat-h: 20 (Khaybar). There is no sahabi equal to Ali in this regard because, leave alone comparison, many of them used to run away from the battlefields whenever odds were against the Holy Prophet, as stated in the commentary of abovenoted verses.
