The importance, value, and blessings inherent in the Dalail Khayraat are not only beyond question, but also beyond understanding and comprehension. Though the arrangement of the various durood could be improved—there are 8 sections for each day of the week, but there are only 7 days in the week—but that said, the text and the recitation make this valuable collection to all and sundry with utmost ease. The persons responsible for the creation of the app deserve our eternal gratitude.
