An offer made in the first person
Allah addresses the son of Adam directly, in two words.
قَالَ اللَّهُ تَبَارَكَ وَتَعَالَى يَا ابْنَ آدَمَ أَنْفِقْ أُنْفِقْ عَلَيْكَ
Allah said: O son of Adam, spend, and I will spend on you. And He said: the hand of Allah is full, and spending does not diminish it.
The full narration
Abu Huraira reported Allah's Messenger (ﷺ) as saying that Allah, the Most Blessed and High, said:O son of Adam, spend. I will spend on you. The right hand of Allah is full and overflowing and in nothing would diminish it, by overspending day and night
