Here is a Dua that we can ask o welcome Ramadan. Consider that the sahabah (Prophet’s companions) and the salaf would be so eager to have their Ibadah accepted that they would pray for up to 6 months after the completion of Ramadan asking Allah to accept their fasts and worships.
Make this Dua to Allah to grant us the days and nights of Ramadan.
