Someone says that according to a Hadith, the hands may be raised when making dua in the Qabrustaan.

Answer

We do not deduct the masaa-il of the Shariah from Ahaadith and the Qur'aan. We are not qualified for this nor is anyone else in the whole world qualified for that. It was the function of the great Imaams of the Khairul

Quroon era to formulate the masaa-il of the Shariah on the basis of the Qur'aan and Hadith. Your friend has no right to dig out a Hadith and present it to negate what the Math-hab teaches.
