بسم الله الرحمن الرحيم
(Fatwa: 239/239/M=1432)
Recite the following dua with durood 7-7 times before and after and blow on your mother:
أسأل الله العظيم ، رب العرش العظيم أن يشفي والدتي شفاءُ كاملاً .
Your mother too should keep on reciting durood. May Almighty Allah cure her completely and make the operation successful!
Allah knows Best!
