Hazrat Moulana Muhammad Ilyaas (rahmatullahi ‘alaih) once mentioned:
In regard to the verse of Surah Mu’minoon in the 18th juz, Allah Ta’ala says:
قَد أَفلَحَ المُؤمِنونَ
“The believers are successful.”
In the following verses, Allah Ta’ala enumerates the qualities of the true believers and explains that those who adopt the qualities of Imaan and lead their lives in conformity to it, they are the ones who are truly successful. Hazrat Moulana then said that in these verses Allah Ta’ala has subjected success and prosperity to Imaan. However, there is no need to confine this success to the Hereafter alone. The promise of Allah Ta’ala also applies to the success of this world. If one inculcates the qualities of Imaan, then just as one will be successful in the Hereafter, one will also be successful in this world and Allah Ta’ala’s divine assistance will be with him.
