ISLAMABAD: Abdul Waqif grips a worn-out shovel and digs into the earth beneath the harsh midday sun, his body bent with age but still moving steadily. Moments later, the 70-year-old hoists a heavy bag of cement onto his shoulders and carries it toward an under-construction house, all while fasting. For Waqif and thousands of daily wage laborers across Pakistan, Ramadan is not just a month of spiritual devotion. It is also a month of shrinking incomes. Waqif migrated from Mohmand tribal district in northwestern Pakistan to Islamabad two decades ago in search of work.
