Allah (swt) says in the Holy Quran:
‘This is the Book about which there is not doubt, a guidance for those conscious of Allah- (TMQ-2:2)
Who believe in the unseen, establish prayer and spend out of what We have provided from them’. (TMQ-2:3)
The Quranic verses mentioned above state that there is no room for any doubt in the Holy Quran because it is completely based on truth. This is not surprising because the Holy Quran is not an ordinary book written by a man but a Divine Book which has been sent down on earth by Allah (swt) who is All-Knowing. The Holy Quran is meant to guide the pious people amongst us, who endeavor to protect themselves from all the evil which Allah (swt) has forbidden and who perform those deeds which Allah (swt) has Commanded us to do. The Holy Quran has also been sent down to guide those amongst us who have faith in the unseen. It is not meant for those who restrict their beliefs only to the material aspects of this world. On the contrary this Holy Book has been sent down to guide those people who believe in Allah (swt and His Revelations, the angels, the Paradise and Hell, the punishment of the grave and the Day of Judgment without actually having seen any of these. So Quran is meant to guide those who possess a strong faith in Allah (swt). The words ‘establishing prayers’ in verse 2:3 refer to punctuality regarding Salaah and offering Salaah according to the Sunnah of the Prophet (saw). It is important to offer Salaah according to the Sunnah of the Prophet because as a matter of fact, the hypocrite Muslims (Munafiqeen) also used to offer Salaah. They had double standards and therefore it is important to establish Salaah according to the Prophetic traditions.
The last part of the verse 2:3 i.e. ‘Spend out of what We have provided them’ includes both the Compulsory charity as well as the Voluntary charity.
So after analyzing verse 2:3 and 2:3, we find that Allah (swt) has categorically stated that the Holy Quran is meant to guide only those people who believe in the unseen, who establish prayers and who spend money in charity. So the Quran is meant to guide only the pious people and one of the signs of such people, as mentioned in verse 2:3, is that they sacrifice a part of their wealth for the betterment of the society. Such people remain detached to their wealth and do not hesitate to give donation or charity if the need arises. They understand that whatever they may spend in the Way of Allah (swt) will be an eternal investment for them. They do not cling on their wealth like niggards because they realize that ultimately, they will have to leave this world empty-handed. Only that part of the wealth can be useful for us, after we leave this world, which had been spent for charity or donation for some Islamic cause. This is evident by the following hadith:
Prophet Mohammad (saw) said, ‘After the death of a person his actions stop except for three things that he leaves behind- continuous charity, beneficial knowledge and a pious son who prays for him’. (Muslim)
