All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
As far as we know, there is no Soorah to recite for the poor to become rich, or for a person to increase his wealth, but Allah, Almighty, has shown to us in His Book that seeking forgiveness is a reason for getting abundant wealth and money, as He Says (what means): {And said, 'Ask forgiveness of your Lord. Indeed, He is ever a Perpetual Forgiver. He will send [rain from] the sky upon you in [continuing] showers. And give you increase in wealth and children and provide for you gardens and provide for you rivers.} [Quran 71:10-12]
Ash-Shawkaani said in Fat'h Al-Qadeer: “This verse is proof that seeking forgiveness is one of the greatest causes of the descent of rain and the occurrence of the different types of provision; that is why Allah said: {And give you increase in wealth and children and provide for you gardens and provide for you rivers.}, i.e. running rivers. Ataa’ said: ‘The meaning is to increase your wealth and your children.’” [End of quote]
Similarly, there are supplications about seeking livelihood and repaying debts, as stated in the Sunnah. For instance, the Prophet said: “O my Lord, Lord of the heavens and Lord of the earth, and Lord of the Mighty Throne, our Lord and the Lord of everything, Who causes the grain and the fruit-stone to split, and who revealed the Torah, the Gospel and the Quran, I seek refuge with You from the evil of everything You hold by the forelock. You are the First before whom there was none, and You are the Last after whom there will be none. You are the Most High above whom there is none, and You are the Inward under whom there is none. Repay my debts and relieve my poverty.” [Al-Bukhari, Muslim, At-Tirmithi, Abu Daawood, and others]
The seeker of abundant livelihood should be God-fearing (have piety) and do righteous deeds, as Allah Says (what means): {And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine.} [Quran 65:2-3]
Allah also Says (what means): {And if only the people of the cities had believed and feared Allah, We would have opened upon them blessings from the heaven and the earth; but they denied [the messengers], so We seized them for what they were earning.} [Quran 7:96]
One should also uphold ties of kinship as the Prophet said: “Whoever wants his age and provision to be extended, then let him uphold good ties with his kinship.” [Al-Bukhari and Muslim]
