Quran on Sadaqah/Saddka

Have you seen the one who denies the Religion? Such is he who repulses the orphan, and who does not urge others to feed the poor. Woe to worshippers, who are absent-minded to their prayer, those who make a show (of piety), and refuse to render small acts of kindness (towards others).(Al-Ma'un 107:1-7)

And spend something (in charity) out of the substance which We have bestowed on you, before Death should come to any of you and he should say, “O my Lord! Why didst Thou not give me respite for a little while? I should then have given (largely) in charity, and I should have been one of the doers of good.” But to no soul will Allah grant respite when the time appointed (for it) has come; and Allah is well-acquainted with (all) that ye do. (Al-Munafiqun 63:10-11)

Saddka should be given solely out of love for God, out of the desire to do good to His creation, as the Quran says about the righteous:"They give food, out of love for Him (Allah), to the poor, the orphan, and the slave, saying: We feed you only for Allah's pleasure - we desire from you neither reward nor thanks." (Al-Insaan 76:8-9)

Giving Saddka will not diminish a Muslim's wealth. It serves as expiation for sins and yields rewards in the next life. Allah says: "For those who give in charity, men and women, and loan to Allah a Beautiful Loan, it shall be increased manifold (to their credit), and they shall have (besides) a liberal reward."(Al-Hadeed 57:18).
