“Believers are merely those whose hearts feel wary whenever God is mentioned and whose faith increases when His verses are recited to them. On their Lord do they rely. Those who keep up prayer and spend some of what We have provided them with are truly believers” (Quran 8:2-4).
Asmah [RA] related that the Prophet [Peace be upon him] said: Spend, and do not count, lest Allah counts against you. Do not withhold your money, lest Allah withholds from you. Spend what you can. (Bukhari, Muslim)
Abu Huraira [RA] related that the Prophet [Peace be upon him] said: The Lord’s commandment for every one of His slaves is, ‘Spend on others, and I will spend on you’. (Bukhari, Muslim)
