Kanchan786: This is indeed very unusual. From Pakistan to Malysia they would be travelling in South-East direction. Why would they be coming first to Doha which is west of Pakistan? As for your query you may need a visit visa for them or you can get them on a tourist visa through any of the leading hotels in Doha. I do not think Qatar Airways would be able to get you a visa but you can check with them or with the Qatar embassy/consulate in Pakistan.
