I want to know what are the major books for supplications? For Shia Muslims, I know the collection book of mafatih-al-jinan with all the supplications from the prophet and the 12 holy household. There, you can see supplication like Kumayl, Munajat Imam Ali, Munajat Shabaniya and much more...
The question is if the sunni scholors consider these supplications to be authentic and if yes, do the Sunni Muslims recite them in daily life? What are the sources of supplications for Sunni Muslims? I need some examples!
