Reciting other duas in the Qunoot of witr
Q: In Mabsoot and Sharhu Mukhtasarul Kharkhy, it comes that qunoot of witr is not a specified dua but it should be as long as Surah Taariq. One Aalim says that if you are in a rush, you can just read rabbana aatina dua, so is this correct? Is it being as long as Suraah Taariq waajib?
