Dua e Mujeer is a highly esteemed supplication, recommended for recitation on the 13th, 14th, and 15th eve of Ramadhan month. It was brought by Angel Jibraeel for the Holy Prophet Muhammad (PBUH) while he was engrossed in prayers in Maqam-e-Ibrahim. The app, developed by Oasis Solutions, provides complete dua e mujeer with English and Urdu translations.

The app is completely offline and does not require an internet connection. It offers audio playback with each line, making it easy to follow along with the Arabic text. The reward for reciting it during the nights of the full moon is that one's sins are forgiven, even if they are in such plenty as the drops of rainwater, leaves of trees, or sand of a desert. The dua is also very effective for the cure of the sick, fulfillment of debts, acquisition of wealth, and relief from sorrows. For every line of dua e mujeer, the app provides the line translation in English, making it accessible for non-native Arabic speakers.
