Allah states that He has perfect knowledge of the good deeds performed by all of His creation, such as charity and various vows, and He rewards tremendously for these deeds, provided they are performed seeking His Face and His promise. Allah also warns those who do not work in his obedience, but instead disobey His command, reject His revelation and worship others besides Him:

وَمَا لِلظَّـلِمِينَ مِنْ أَنصَارٍ

(And for the wrongdoers there are no helpers.) meaning, who will save them from Allah's anger and torment on the Day of Resurrection.

(4) Verse 270: وَمَا أَنفَقْتُم مِّن نَّفَقَةٍ (الی قولہ) وَمَا لِلظَّالِمِينَ مِنْ أَنصَارٍ‌: "And whatever spending you do ... and for the unjust, there are no supporters."

Here, "and whatever spending you do" covers all spendings - those in which all related conditions are observed and those too, in which all or some conditions are not observed. For instance, it may not be in the way of Allah but be in the ways of sin; or the act of giving may be mixed up with hypocrisy; or may be followed by making a show of the favour before the receiver; or it may not be حلال halal (lawful) and good.
