This story is narrated by a doctor himself :
 
I am an Egyptian Doctor. I got a severe and dangerous illness in my heart. So I went to London for further treatment. After checking my body, the expert doctors reported that we could not recognize your illness.
> So immediately you must take risky surgery in your heart, You may live or not live, we can't assure it.
>
> I came back to Egypt sadly before taking surgery because I lost my confidence as I considered that I would pass away. And I decided to fulfill my credits and duties quickly. First I went to a butcher shop where
> I have to pay my account. At that time, I saw a poor woman was collecting the broken bones and fleshes that were falling down.
>
> I asked her "what is this? Why do you take these dirty fleshes and bones? She replied "I have five children, since one year they did not taste a bit of flesh because of poverty, Let them smell these fleshes and bones, she replied.
>
> My heart was broken after hearing her poverty . Then I said to the butcher "give her two kilo fleshes weekly once in my account" ! She said “no". After a lot of persuasion, she said with tears in her eyes "Only one kilo is enough" "Please get two kilo per week” I replied. Then I paid to the butcher full amount of flesh as advance for one year. She wept and made Dua (prayer) for myself more and more. Then I returned to house. My
daughter smiled and asked, "Dad! What happened? I think you are happy!"
 
 "Yes! Now I feel very happy and full of satisfaction in my heart." Then I narrated what happened in the butcher shop. My daughter’s eyes got wet. She also made Dua (prayer) for me. However then I was feeling well in my body and mind. Later on few weeks I went to London for the surgery. The surgeon amazingly asked me after rechecking the body, "where did you get treatment Sir? In which Hospital you took surgery? Who is that erudite doctor?"
 
 I replied, "I did not go to any doctor, I just went for fulfill my duties, that’s all !" The doctor said "Sir, Now You have no problem at all!" I asked surprisingly "what do you say?" " Yes. Definitely You have no illness in your heart. If you doubt my checking go to another expert doctor! "
 
 Then I came back to house and said to my daughter, Allah has shown and poured his mercy upon myself. Both of us thanked Allah more.
 
 
 
  *One thing we have to understand from this story, *
  *وَمَا تُقَدِّمُوا لِأَنْفُسِكُمْ مِنْ خَيْرٍ تَجِدُوهُ عِنْدَ اللَّهِ هُوَ
> خَيْرًا وَأَعْظَمَ أَجْرًا***
 
 And [remember] Whatever good you send forth for yourselves you shall find it with Allah better than before and greater in reward. (73:20)
