Infaq (Charity) is mentioned almost 60 times in the Quran. Allah commands this basic pious spending for His sake on all of human beings. Through Infaq, the redistribution of wealth contributes to the eradication of poverty in our communities. Infaq also provides numerous benefits and securities for the giver, as long as all conditions are met.
The return can go to more than 700 times the initial amount (Quran 2:261) - The example of those who spend their wealth in the way of Allah is like a seed which grows seven spikes; in each spike is a hundred grains. And Allah multiplies for whom He wills. And Allah is all-Encompassing and Knowing.
"When a person dies, all their deeds end except three: a continuing charity, beneficial knowledge and a child who prays for them," (Hadith, Muslim).
Therefore, Muslims are eager to give charity which will continue to have benefit to people after their death and continue to earn them reward.
