When the verse,
مَّن ذَا الَّذِى يُقْرِضُ اللَّهَ قَرْضًا حَسَنًا فَيُضَاعِفَهُ لَهُ أَضْعَافًا كَثِيرَة
“Who is it that will lend unto Allah a goodly loan, so that He may give it increase manifold?”3,
was revealed, Abu Dahdaah4 said: O’ Prophet of God! May I be made your ransom! How is it that while God is Independent and Needless, He seeks from us a loan?
The Holy Prophet (peace be upon him and his holy progeny) replied: It is because He desires to make you enter Paradise by means of this.
Abu Dahdaah asked: If I give my God a loan, do you guarantee Paradise for me?
Yes. Whoever gives God a loan, God shall recompense him in Paradise, the Holy Prophet (peace be upon him and his holy progeny) replied.
Abu Dahdaah continued: Would my wife, Umme Dahdaah be with me in Paradise?
The Holy Prophet (peace be upon him and his holy progeny) said: Yes.
Abu Dahdaah persisted: Would it be that my daughter too shall be with me in Paradise?
This time, as the Holy Prophet (peace be upon him and his holy progeny) replied in the affirmative, Abu Dahdaah said to him (peace be upon him and his holy progeny): Place your hand upon my hand to confirm what you have just stated!
The Holy Prophet (peace be upon him and his holy progeny) gave him his hand, whereupon he said: I have nothing but two gardens and I lend both of them to God.
The Holy Prophet (peace be upon him and his holy progeny) however advised: Keep one for yourself and lend the other.
When he heard this, Abu Dahdaah said: I take you, the Prophet of God, to be my witness that I have given the best of the two gardens as loan to God.
That garden contained six hundred date palms!
The Holy Prophet (peace be upon him and his holy progeny) said to him: God has granted you Paradise in exchange for it.
When Abu Dahdaah informed his wife of the incident, she said to him: May God make blessed that which you have purchased for yourself.( U’nwaan al-Kalaam, pg. 175. )
