When we do something for the sake of Allah, we are not sacrificing anything because sacrificing means we are giving something up without any returns (e.g. sometimes we say, “sacrifice your sleep to stand up in the night”).
In fact, it’s a two-way contract. Whenever you do a good deed with the correct niyyah (intention), the reward is confirmed. If you are not rewarded in this life, you will definitely see the fruits of your deed in the Hereafter.
