Here's a humble prayer (Dua) to seek prosperity and wealth from Allah:
"O Allah, grant me wealth and prosperity in this life, and guide me to use it wisely and charitably. Make me grateful for Your blessings and increase my wealth in a halal (permissible) way, without making it a distraction from Your remembrance and my duties towards You. May my wealth be a source of comfort, security, and happiness for me and my loved ones, and may I use it to benefit others and earn Your pleasure. Ameen."
Remember, true wealth lies in a content heart, good health, and a strong connection with Allah. May Allah bless you with abundance and guide you to use it for the greater good!
(Note: Wealth and billionaireship are not the ultimate goals in Islam. The focus is on living a righteous life, being content, and using one's resources to benefit humanity and seek Allah's pleasure.)
