A'amaal-2 Taken from Mawaiiz-e-Hasana of Hadhrat Muhaddith-e-Deccan (May Allah SWT shower His Mercy on him)

Hadhrat Salman Farsi (May Allah SWT be well pleased with him) said that the Holy Prophet (Sallallahu alaihi wa sallam) said: Don’t be formal. Do not shy away from offering the guest whatever is present. The Sahabah used to place a piece of bread and dry dates in front of each other and used to say: We do not know that which person is a sinner – the one who considers whatever is present as cheap and does not place it in front of the guest or the person before whom it is placed and he considers it as cheap.

In the past, whenever Muslims were guided towards good deeds they would offer some alms/money in charity to thank Allah SWT and would not desire anything from the creation in lieu of this good deed.

A certain pious person went to the market to buy something. He asked the price, the shopkeeper said: The price for this is 4 pice, but for you I will give in 3. That pious person started crying. He said: My piousness is worth only 1 pie. He said: I don’t sell my religion. I did not acquire religion (Deen) to gain something from the creation (makhlooq)

The Prophets (peace be upon them) used to say:
Translation: I do not ask you for any wealth for this
Translation: I do not want any return from you.
Nowadays Muslims participate in the festivals of non-Muslims and ask them participate in their festivals (eid). This is similar to what the people of Makkah said to the Holy Prophet (Sallallahu alaihi wa sallam) that one year you follow our religion and one year we will follow your religion. On this this verse was revealed:
Translation: Your religion for you and our religion for us.
