Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
There is no harm in asking Allah Ta‘ala to grant one an abundance of wealth. However, together with that, one should beseech Allah Ta’ala to grant Him His special grace and barakah (divine blessings). In this way, the wealth he receives will be a means of blessings in his life. Otherwise, just an abundance of wealth without blessings can become a source of misfortune and punishment for a person through utilizing the wealth in wrong avenues.
