Good Character

Lying to one's mother

Q: I told a lie to my mom that I passed my paper because she takes too much tension. Just to avoid her depression I told her that I passed and now she is offering 50 nafal of shukr... I regret telling a lie but I am afraid to tell her the truth. What should I do?

Saying that someone is busy when answering a call

Q: I served in a Pvt Limited Company. Part of my job is to receive phone calls and to transfer it to my senior's and boss. Sometimes, I receive a phone call and when I transfer it to my boss, he tells me to tell the caller that he is busy in meeting or not available in the office whereas he is free and present. The issue is, it is a lie. Will I be sinning for speaking lies?

Does making fun of another language result in making fun of the signs of Allah

Q: "And among the signs of His power is the creation of the heavens and the earth and diverse language and skin color. Surely, with that situation actually there are signs for people who know" (Ar-Rum:22)

According to an intrepretation. If I make fun of someone speaking in other language which seems funny, is it as if I made fun of a language (Allah's sign) and thereby kufr?
