Hadhrat Abu Sa'eed رضي الله عنه reports that a Bedouin once came to Rasulullaah

to demand payment of a debt Rasulullaah

owed to him. He behaved very harshly with Rasulullaah

saying, "I shall continue plaguing you until you pay the debt!" The companions of Rasulullaah

admonished the man saying, "Shame on you! Do you know with whom you are talking?!" The man said, "I am only asking for my right." Rasulullaah

said to them, "Why are you not defending the one who has a right?"
Rasulullaah

then sent for Hadhrat Khowla bint Qais :ra: and asked her, "Borrow me some dates if you have any and I shall pay you back when I receive some dates." She said, "Most certainly! May my parents be sacrificed for you, O Rasulullaah

!" She then borrowed the dates to Rasulullaah

, with which he paid the Bedouin off together with something extra. The man then said, ''You have given me full payment, may Allaah :swt1: give you in full." Rasulullaah

then said, "They are the best of people (who support those with a right). There is no good in a nation whose weak people cannot claim their right without hesitation."
The Narration of Hadhrat Khowla bint Qais :ra: in this Regard
Hadhrat Khowla bint Qais who was the wife of Hadhrat Hamza bin Abdul Muttalib رضي الله عنه narrates, "Rasulullaah

owed a wasaq of dates to a man from the Banu Saa'idah tribe. When the man came to claim repayment, Rasulullaah

instructed someone from the Ansaar to pay it. When the Ansaari paid the man in dates which were of an inferior quality, he refused to accept it. The Ansaari said, "Are you refusing Rasulullaah

?" The man said, "Yes. Who is more worthy of exercising justice than Rasulullaah

?" Rasulullaah 's

eyes welled with tears as he said, "He is right. Who is more worthy of exercising justice than me? May Allaah not bless a nation whose weak ones cannot claim their rights from their powerful ones and cannot demand them either." Rasulullaah

then said, "O Khowla! Count and settle his debt because when a creditor is satisfied when he leaves his debtor, all creatures on earth and fish in the oceans pray for him (the debtor). However, when a debtor delays in paying when he has the means to pay, Allaah :swt1: records a sin in his records for every day and night that passes (without him paying)."
