I am writing this post in response to a kind suggestion of Juan who asked me to write a post about cultural expressions and their replies. Thank you very much Juan for the suggestion! I think that this is a very important topic. Please find a list below. 
 
 بسم الله 
 
 “Bismillah” literally means (in the name of God). We use it when we start something, e.g. at the beginning of a meal. 
 
 الحمد لله 
 
 “Alhamdu-lillah” literally means (Thank God). We use it when we finish something, e.g. at the end of a meal. It is also used when we are grateful for something or when something good happens to us. 
 
 ما شاء الله 
 
 “Maa shaa’ Allah” literally means (what God wants is done). We use it when we appreciate something, e.g. if my friend shows me something nice or new, I say this expression. 
 
 مبروك 
 
 “Mabrook” means (congratulations). We use it in happy occasions, e.g. if some one gets married or succeeds in an exam, etc. The reply is (الله يبارك فيك) 
 
 الحمد لله 
 
 “Alhamdu-lillah” is also used after sneezing, i.e. when I sneeze, I say “Alhadu-lillah”. The reply is (يرحمكم الله) 
 
 السلام عليكم 
 
 “Assalamu ‘alaykum” is a greeting you say when you meet someone. The reply is (وعليكم السلام) 
 
 البقاء لله 
 
 “Albaqa’ Lillah” is used to convey condolences. 
 
 الله يرحمه/يرحمها 
 
 “Allah yarhamu/yarhamha” is used after the name of someone who passed away. ||||| Omar Sharif, star of Dr Zhivago and one of the world's greatest bridge players, has died aged 83. 
 
 His agent Steve Kenis said on Friday: "He suffered a heart attack this afternoon in a hospital in Cairo." 
 
 Egyptian-born Sharif, who had Alzheimer’s disease, won international acclaim for his role in David Lean’s 1962 epic Lawrence of Arabia. 
 
 It was his first English-language film and his turn as Sherif Ali won him two Golden Globes and an Oscar nomination. 
 
 Sharif later took the title role in Lean’s Doctor Zhivago, co-starring Julie Christie, for which he won another Golden Globe award. 
 
 He then played Fanny Brice’s husband, Nicky Arnstein, in Funny Girl alongside Barbara Streisand. 
 
 But although he starred in dozens of films, his career never quite lived up to its early promise and his later fame rested on his ability with a pack of cards. 
 
 Sharif was a regular in casinos and one of the world's best bridge players.

 In May, Sharif's son Tarek El-Sharif, revealed that his father had Alzheimer's and confused the names of his best known films. 
 
 He said the actor mistook fans for people he used to know. 
 
 "My father has Alzheimer's," the 58-year-old told Spanish newspaper El Mundo. 
 
 "It's difficult to determine what stage. It's obvious he won't improve and will get worse."

 He said that his father, who had recently spent most of his time in his native Egypt, struggled with details in particular. 
 
 "He remembers for example that it was Doctor Zhivago but he's forgotten when it was filmed," he added. 
 
 "He can talk about the film but he forgets its name or he calls it something else like Lawrence Of Arabia." 
 
 Mr El-Sharif, the actor's only child with his ex-wife of 20 years Faten Hamama, said his father did not recognise that he was ill. 
 
 He was unaware that his former wife had died in January. 
 
 The pair had met on set and Sharif, who was born Michel Demetri Chalhoub, is said to have changed his name when he married her and converted to Islam.

 Sharif attended boarding school in Cairo, where he developed a taste for acting. 
 
 He went on to gain a degree in mathematics and physics from Cairo University and became one of the top 10 bridge players in the world. 
 
 But he once claimed that he was "always one film behind my debts". 
 
 He is said to have lost a £4million villa on the Spanish island of Lanzarote in a bridge game in the 1970s.

 Gambling took its toll on his career and, speaking in 2004, Sharif said he stopped making films when his own grandchildren started making fun of the low-rent movies he was appearing in. 
 
 He said: "I stopped making movies because for the last 25 years I've been making a lot of rubbish because I was in debt all the time". 
 
 The actor spent much of his life living in hotels and was reportedly living in one in the Red Sea resort of El Gouna as recently as May. 
 
 His son said his father felt "insecure" when he left the hotel and often refused to come out of his room.
– Omar Sharif, the dashing Egyptian actor who rose to fame in America in 1962's Lawrence of Arabia and 1965's Doctor Zhivago—both directed by David Lean—has died at the age of 83, the AP reports. His longtime agent tells the news agency that Sharif died of a heart attack in a Cairo hospital. His grandson Omar Sharif Jr., who had just last week posted a photo of himself and his grandfather on Facebook with the message "I love you," simply tweeted this morning, "Al-Baqa Lillah," an Arab expression used to convey condolences. The Telegraph reports that Sharif had suffered from Alzheimer's, and in May his only child, Tarek El-Sharif told the Spanish newspaper El Mundo his dad couldn't remember certain details about his films. "He remembers, for example, that it was Doctor Zhivago but he's forgotten when it was filmed," El-Sharif said. Sharif garnered an Oscar nomination for his turn as Sherif Ali in Arabia, even though he wasn't Lean's first choice—the actor Lean had picked was rejected for having the wrong eye color, per NBC News. Sharif was brought back by Lean for Zhivago then went on to rack up more than 100 acting credits, including roles as Mongol chief Genghis Khan in the 1965 eponymous movie, Che Guevara in 1969's Che!, and as a gambler in Funny Girl with Barbra Streisand, a movie that was banned in Egypt because Sharif played a Jew, NBC reports. The Telegraph notes he was also known as "one of the world's greatest bridge players."
