What Is The Difference Between These Ayah And Why Rewards Are Different?
It is true that these factors are not mentioned in these verses directly. However, they can inferred from other verses of the Quran. These verses mention the generosity of God on the people who turn toward Him and there’s no reason for God to limit his generosity to a single ratio only. Besides, it is only logical and because of God’s attrubute of Justice and Wisdom, that reward distrubution should vary ( so does the God’s generosity ) depending upon the nature of the deed, the time in which it is done and the internal and external circumstances of those who do the deed. The same has been done in Quran as well, where distinctions have been drawn between Sabiqoon-al-awwaloon , Shuhada , Siddiqeen and the others. They were given higher ranks becasue of the very factors. Somewhat similar distinction can be seen in Quran 49:14-15 : قَالَتِ الْأَعْرَابُ آمَنَّا قُل لَّمْ تُؤْمِنُوْا وَلَكِن قُوْلُوْا اَسْلَمْنَا وَلَمَّا يَدْخُلِ الْإِيمَانُ فِیْ قُلُوْبِكُمْ وَاِنْ تُطِيعُوا اللّٰهَ وَرَسُوْلَهُ لَا يَلِتْكُمْ مِّنْ اَعْمَالِكُمْ شَيْئًا إِنَّ اللّٰهَ غَفُوْرٌ رَّحِيْمٌ. اِنَّمَا الْمُؤْمِنُوْنَ الَّذِيْنَ آمَنُوْا بِاللّٰهِ وَرَسُوْلِهِ ثُمَّ لَمْ يَرْتَابُوْا وَجَاهَدُوْا بِاَمْوَالِهِمْ وَاَنفُسِهِمْ فِیْ سَبِيْلِ اللّٰهِ اُوْلَئِكَ هُمُ الصَّادِقُوْنَ. [While expressing favour to you,] these Bedouins [who call out to you from outside your quarters] say: “We profess faith.” Tell them: You have not professed faith. Indeed, what you can say is: “We have become obedient.” Faith has not even entered your hearts as yet. If you obey God and His messenger, God shall not make any reduction in your deeds. [So, reform your selves.] God certainly is Forgiving, Ever-Merciful. [Remember that] believers in reality are only those who professed faith in God and His Messenger, then were not afflicted with doubt and fought in the way of God through their wealth and their persons. It is these who are the truthful . Here, in this case, distinction has been drawn between obedience and faith. And basic reward scheme has been described i.e. “ God shall not make any reduction in your deeds ” instead of multiplied rewards in this case because of the same factors that are present in this case thus soliciting a mention of basic reward scheme.
