أَضْعَافًا aḍʿāfan · manifolds

Who is it that would loan Allāh a goodly loan so He may multiply it for him many times over? And it is Allāh who withholds and grants abundance, and to Him you will be returned. (Surah Al-Baqarah, 2:245)

وَمَثَلُ الَّذِينَ يُنفِقُونَ أَمْوَالَهُمُ ابْتِغَاءَ مَرْضَاتِ اللَّهِ وَتَثْبِيتًا مِّنْ أَنفُسِهِمْ كَمَثَلِ جَنَّةٍ بِرَبْوَةٍ أَصَابَهَا وَابِلٌ فَآتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِن لَّمْ يُصِبْهَا وَابِلٌ فَطَلٌّ وَاللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ ٢٦٥

ضِعْفَيْنِ ḍiʿ'fayni · double

And the example of those who spend their wealth seeking means to the approval of Allāh and assuring [reward for] themselves is like a garden on high ground which is hit by a downpour - so it yields its fruits in double. And [even] if it is not hit by a downpour, then a drizzle [is sufficient]. And Allāh, of what you do, is Seeing. (Surah Al-Baqarah, 2:265)

مَّثَلُ الَّذِينَ يُنفِقُونَ أَمْوَالَهُمْ فِي سَبِيلِ اللَّهِ كَمَثَلِ حَبَّةٍ أَنبَتَتْ سَبْعَ سَنَابِلَ فِي كُلِّ سُنبُلَةٍ مِّائَةُ حَبَّةٍ وَاللَّهُ يُضَاعِفُ لِمَن يَشَاءُ وَاللَّهُ وَاسِعٌ عَلِيمٌ ٢٦١

يُضَاعِفُ yuḍāʿifu · gives manifold

The example of those who spend their wealth in the way of Allāh is like a seed [of grain] which grows seven spikes; in each spike is a hundred grains. And Allāh multiplies [His reward] for whom He wills. And Allāh is all-Encompassing and Knowing. (Surah Al-Baqarah, 2:261)

أَيَوَدُّ أَحَدُكُمْ أَن تَكُونَ لَهُ جَنَّةٌ مِّن نَّخِيلٍ وَأَعْنَابٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ لَهُ فِيهَا مِن كُلِّ الثَّمَرَاتِ وَأَصَابَهُ الْكِبَرُ وَلَهُ ذُرِّيَّةٌ ضُعَفَاءُ فَأَصَابَهَا إِعْصَارٌ فِيهِ نَارٌ فَاحْتَرَقَتْ كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمُ الْآيَاتِ لَعَلَّكُمْ تَتَفَكَّرُونَ ٢٦٦

ضُعَفَاءُ ḍuʿafāu · (are) weak

Would one of you like to have a garden of palm trees and grapevines underneath which rivers flow in which he has from every fruit? But he is afflicted with old age and has weak [i.e., immature] offspring, and it is hit by a whirlwind containing fire and is burned. Thus does Allāh make clear to you [His] verses that you might give thought. (Surah Al-Baqarah, 2:266)

قَالَ الْمَلَأُ الَّذِينَ اسْتَكْبَرُوا مِن قَوْمِهِ لِلَّذِينَ اسْتُضْعِفُوا لِمَنْ آمَنَ مِنْهُمْ أَتَعْلَمُونَ أَنَّ صَالِحًا مُّرْسَلٌ مِّن رَّبِّهِ قَالُوا إِنَّا بِمَا أُرْسِلَ بِهِ مُؤْمِنُونَ ٧٥

اسْتُضْعِفُوا us'tuḍ'ʿifū · were oppressed

Said the eminent ones who were arrogant among his people to those who were oppressed - to those who believed among them, "Do you [actually] know that Ṣāliḥ is sent from his Lord?" They said, "Indeed we, in that with which he was sent, are believers." (Surah Al-A'raf, 7:75)

وَمَا لَكُمْ لَا تُقَاتِلُونَ فِي سَبِيلِ اللَّهِ وَالْمُسْتَضْعَفِينَ مِنَ الرِّجَالِ وَالنِّسَاءِ وَالْوِلْدَانِ الَّذِينَ يَقُولُونَ رَبَّنَا أَخْرِجْنَا مِنْ هَٰذِهِ الْقَرْيَةِ الظَّالِمِ أَهْلُهَا وَاجْعَل لَّنَا مِن لَّدُنكَ وَلِيًّا وَاجْعَل لَّنَا مِن لَّدُنكَ نَصِيرًا ٧٥

وَالْمُسْتَضْعَفِينَ wal-mus'taḍʿafīna · and (for) those who are weak

And what is [the matter] with you that you fight not in the cause of Allāh and [for] the oppressed among men, women, and children who say, "Our Lord, take us out of this city of oppressive people and appoint for us from Yourself a protector and appoint for us from Yourself a helper"? (Surah An-Nisa, 4:75)
