Sadaqah in Quran
خُذْ مِنْ أَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِم بِهَا وَصَلِّ عَلَيْهِمْ إِنَّ صَلَاتَكَ سَكَنٌ لَّهُمْ وَاللَّـهُ سَمِيعٌ عَلِيمٌ )توبہ ۱۰۳(
Take alms out of their property, you would cleanse them and purify them thereby, and pray for them; surely your prayer is a relief to them; and Allah is Hearing, Knowing.
إِن تُبْدُوا الصَّدَقَاتِ فَنِعِمَّا هِيَ وَإِن تُخْفُوهَا وَتُؤْتُوهَا الْفُقَرَاءَ فَهُوَ خَيْرٌ لَّكُمْ وَيُكَفِّرُ عَنكُم مِّن سَيِّئَاتِكُمْ وَاللَّـهُ بِمَا تَعْمَلُونَ خَبِيرٌ ﴿بقرۃ ٢٧١﴾
If you give alms openly, it is well, and if you hide it and give it to the poor, it is better for you; and this will do away with some of your evil deeds; and Allah is aware of what you do.
لَّا خَيْرَ فِي كَثِيرٍ مِّ نَّجْوَاهُمْ إِلَّا مَنْ أَمَرَ بِصَدَقَةٍ أَوْ مَعْرُوفٍ أَوْ إِصْلَاحٍ بَيْنَ النَّاسِ وَمَن يَفْعَلْ ذَٰلِكَ ابْتِغَاءَ مَرْضَاتِ اللَّـهِ فَسَوْفَ نُؤْتِيهِ أَجْرًا عَظِيمًا ﴿نساء ١١٤﴾
There is no good in most of their secret counsels except (in his) who enjoins charity or goodness or reconciliation between people; and whoever does this seeking Allah's pleasure, We will give him a mighty reward.
وَمِنْهُم مَّنْ عَاهَدَ اللَّـهَ لَئِنْ آتَانَا مِن فَضْلِهِ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ الصَّالِحِينَ فَلَمَّا آتَاهُم مِّن فَضْلِهِ بَخِلُوا بِهِ وَتَوَلَّوا وَّهُم مُّعْرِضُونَ )توبہ ۷۵۔۷۶(
And there are those of them who made a covenant with Allah: If He give us out of His grace, we will certainly give alms and we will certainly be of the good, But when He gave them out of His grace, they became niggardly of it and they turned back and they withdrew.
وَأَنْفِقُوا مِنْ مَا رَزَقْنَاكُمْ مِنْ قَبْلِ أَنْ يَأْتِيَ أَحَدَكُمْ الْمَوْتُ فَيَقُولَ رَبِّ لَوْلا أَخَّرْتَنِي إِلَى أَجَلٍ قَرِيبٍ فَأَصَّدَّقَ وَأَكُنْ مِنْ الصَّالِحِينَ(منافقون آیت ۱۰)
And spend out of what We have given you before death comes to one of you, so that he should say: My Lord! why didst Thou not respite me to a near term, so that I should have given alms and been of the doers of good deeds?
