Assalam Alaikum dear friend, you have written a very loving letter to your father and I am very happy to know that you loved your father very much. They knew and had good knowledge and they trained you very well and they wanted you to work hard and earn your livelihood through hard work and this effort proved successful. You are a very dedicated person and steadfast. That is why Allah Almighty has given you success and all the credit goes to your Abu ji.
