Strained yoghurt (also spelled strained yogurt), yoghurt cheese, labneh, or Greek yoghurt is yoghurt which has been strained in a cloth or paper bag or filter to remove the whey, giving a consistency between that of yoghurt and cheese, while preserving yoghurt's distinctive sour taste. Like many yoghurts, strained yoghurt is often made from milk which has been enriched by boiling off some of the water content, or by adding extra butterfat and powdered milk.

Yoghurt strained through muslin is a traditional food in the Levant, Eastern Mediterranean, Near East, and South Asia, where it is often used in cooking, as it is high enough in fat not to curdle at higher temperatures. It is used in both cooked and raw, savoury and sweet dishes. Due to the straining process to remove excess whey, even non-fat varieties are rich and creamy.

In Western Europe and the U.S., strained yoghurt has become increasingly popular because it is richer in texture than unstrained yoghurt, but low in fat. Since straining removes whey, strained yoghurt is higher in protein and lower in sugar and carbohydrates than unstrained yoghurt.

Ahmad Wali (Pashto/Persian: احمد ولی‎) is a popular Ghazal singer from Afghanistan. He began his career in the 1970s, becoming popular in his native country before he was forced to flee by political upheaval in Afghanistan. He continued his work after resettling in Germany, performing throughout Europe and the United States.

The son of a Police Commander, Wali was born in Kabul. He began exploring music as a Tabla player at the age of 12, gradually expanding into singing. While a student at Habibia High School, he recorded a demo tape. This came to the attention of Radio Kabul director Ustad Zaland, who wrote the song "Chashman -e -Abee" for Wali. This and the Wali-penned tune "Mah-ruye-tu" brought him to the public eye. Wali performed live in Afghanistan until after his high school graduation, when he joined an international performance in Iran.

At that early stage in his career, Wali had not yet committed to life as a professional musician, and he enrolled in the Kabul Police Academy. He continued performing, however, and soon committed to music, being taken as a student by classical musician Ustad Sarahang. He developed a following in Afghanistan, with frequent appearances on television and radio as well as live performances.
