The Ruling on Joking with One's Parents

Question:
I, praise be to Allah, seek forgiveness frequently, and I make du'a' for my parents in prayer and otherwise. However, sometimes I joke with them using words that contain no anger, and I try to do this to make them happy, to complete their happiness, and to earn their pleasure with me. They are, praise be to Allah, pleased with me. Is it permissible to joke with them, or is it not permissible? And what is the ruling if I call my father "so-and-so" without saying "my father," and the same for my mother?

Answer:
Joking with the truth, if it is little, does no harm, if it is joking, meaning it makes them happy and broadens their minds with truth, not with lying or harm; there is nothing wrong with it. But the one who jokes should not say anything but the truth, and he should not overdo it so that it does not lead to evil.
And the Sunnah is to call him by the name he loves most, such as "Abu so-and-so," or "O my father," "O my father," or "O Abu so-and-so" if he likes that, "O Abu 'Abdullah," "O Abu 'Abd al-Rahman," "O Abu Ibrahīm."
