Allah is the Provider
When it comes to material goods, Allah (swt) is the One who provides us with what we need: food, clothing, etc. The hadith shows the generosity of Allah (swt). The more we ask Him, the more He gives us. He wants us to come closer to Him by expressing our needs with humility. Allah (swt) said: "Do not seek sustenance from anyone other than Me, for verily all those others from whom you might seek sustenance have themselves been provided for by Myself. So seek sustenance from me and I will provide for you"
