What is the reward for helping others with the intention of seeking recompense and bringing joy, and are there any hadiths, evidences, or stories that encourage this, especially the hadith that means: "The most beneficial of you to people"? And is helping others more rewarding than the remembrance of Allah?

Helping others is one of the greatest doors to goodness in Islam, and it is considered an act of worship for which one is rewarded if it is done purely for the sake of Allah. A Muslim can intend many good intentions with it, as long as they do not contradict sincerity. However, if the help is motivated by personal gain, such as seeking praise, then there is no reward for it in the Hereafter.

Among the virtues of helping others are: it is a form of Ihsan (kindness) that Allah loves; whoever fulfills the need of his brother, Allah will fulfill his need; good deeds protect against evil fates; the most beloved people to Allah are those most beneficial to people; and the most beloved deeds to Allah are bringing joy to a Muslim or relieving his distress.

Helping others may even be better than dhikr (remembrance of Allah) if there is a needy person who cannot find anyone to help them other than the inquirer, or if the Muslim is responsible for helping others, because the benefit that extends to others is superior to the benefit that is limited to oneself.
