Allah said:

﴿مَّن ذَا الَّذِى يُقْرِضُ اللَّهَ قَرْضًا حَسَنًا فَيُضَاعِفَهُ لَهُ أَضْعَافًا كَثِيرَةً﴾

(Who is he that will lend to Allah a goodly loan so that He may multiply it to him many times)

In this Ayah, Allah encourages His servants to spend in His cause. Allah mentioned this same Ayah in several other parts of His Glorious Qur'an. The Hadith that mentions that Allah descends (every night down on the nearest heaven to us when the last third of the night remains) states that Allah says:

«مَنْ يُقْرِضُ غَيْرَ عَدِيمٍ وَلَا ظَلُوم»

(Who would give a loan to He Who is neither poor nor unjust.)

Allah's statement:

﴿فَيُضَاعِفَهُ لَهُ أَضْعَافًا كَثِيرَةً﴾

(He may multiply it to him many times), is similar to His statement:

﴿مَّثَلُ الَّذِينَ يُنفِقُونَ أَمْوَلَهُمْ فِي سَبِيلِ اللَّهِ كَمَثَلِ حَبَّةٍ أَنبَتَتْ سَبْعَ سَنَابِلَ فِي كُلِّ سُنبُلَةٍ مِّاْئَةُ حَبَّةٍ وَاللَّهُ يُضَـعِفُ لِمَن يَشَآءُ﴾

(The likeness of those who spend their wealth in the way of Allah, is as the likeness of a grain (of corn); it grows seven ears, and each ear has a hundred grains. Allah gives manifold increase to whom He wills.) (2:261)

We will mention this Ayah later on. Allah then said:

﴿وَاللَّهُ يَقْبِضُ وَيَبْسُطُ﴾

(And it is Allah that decreases or increases (your provisions), ) meaning, `Spend (in Allah's cause) and do not be anxious.' Certainly, Allah is the Sustainer Who increases or decreases the provisions to whomever He wills among His servants. Allah's wisdom is perfect, and,

﴿وَإِلَيْهِ تُرْجَعُونَ﴾

(and unto Him you shall return.) on the Day of Resurrection.

﴿أَلَمْ تَرَ إِلَى الْمَلإِ مِن بَنِى إِسْرءِيلَ مِن بَعْدِ مُوسَى إِذْ قَالُواْ لِنَبِىٍّ لَّهُمُ ابْعَثْ لَنَا مَلِكًا نُّقَـتِلْ فِى سَبِيلِ اللَّهِ قَالَ هَلْ عَسَيْتُمْ إِن كُتِبَ عَلَيْكُمُ الْقِتَالُ أَلاَّ تُقَـتِلُواْ قَالُواْ وَمَا لَنَآ أَلاَّ نُقَـتِلَ فِى سَبِيلِ اللَّهِ وَقَدْ أُخْرِجْنَا مِن دِيَـرِنَا وَأَبْنَآئِنَا فَلَمَّا كُتِبَ عَلَيْهِمُ الْقِتَالُ تَوَلَّوْاْ إِلاَّ قَلِيلاً مِّنْهُمْ وَاللَّهُ عَلِيمٌ بِالظَّـلِمِينَ ﴾

(246. Have you not thought about the group of the Children of Israel after (the time of) Musa When they said to a Prophet of theirs, "Appoint for us a king and we will fight in Allah's way.'' He said, "Would you then refrain from fighting, if fighting was prescribed for you'' They said, "Why should we not fight in Allah's way while we have been driven out of our homes and our children (families have been taken as captives)'' But when fighting was ordered for them, they turned away, all except a few of them. And Allah is All-Aware of the wrongdoers.)
