The Prophet, peace and blessings of Allah be upon him, said:
“Make the orphan come close to you, and be nice to him, and wipe his head, and feed him your food. That will cause your heart to be soft, and your needs to be fulfilled.” (Recorded in al-Tabarani)
Once Anas ibn Malik was asked by someone to make du’a for him. He replied, “Verily, du’a is raised up (to Allah) by good deeds,” indicating that the questioner should strive to perform good deeds if they want their du’a to be answered. And Wahb ibn Munabih said: “The example of the one who makes du’a without doing any deeds is like the one who tries to shoot arrows without a bow.”
So if we wish our du’a to be responded to, we should increase the quality of the good deeds that we do.
