It was the usual practice of Umar that he would patrol the streets and suburbs of Madina to watch the interests of the people, and attend to their needs.
One day Umar noticed a tent pitched in an open space outside Madina. A person was sitting outside the tent, and some one inside the tent was groaning.
Umar went to the man, greeted him, and wanted to know who he was.
The man said that he was a man of the desert, and had come to Madina to wait on the Commander of the Faithful and seek his assistance.
Umar next asked who was groaning inside the tent. The man said that inside the tent his wife was groaning with labour pains. He said that he was a stranger in Madina and did not know what to do. Umar enquired whether he had any woman to look after the confinement of his wife. He said that there was none.
Umar said, "Do not worry. I will make the necessary arrangements."
Umar came home, and asked his wife Umm Kulsum to accompany him on a mission of service. Umm Kulsum got ready and took with her such things as might be needed for the purposes of confinement. Umar took with him some provisions for the purposes of cooking a meal.
Umar returned to the camp with his wife. Umm Kulsum went inside the tent to attend to the woman in pain, while Umar sat outside the tent with the Bedouin and began cooking some meals for him.
After an hour or so when the meals had been cooked, Umm Kulsum from inside the tent addressed Umar: Amirul Mominin! Congratulate your guest on the birth of a son."
Hearing this the Bedouin felt much embarrassed. Turning to Umar he said, "Amirul Mominin, why did you not reveal your identity? You have overwhelmed me with your benevolence."
Umar put all his fears to rest saying: "That's all right. There is nothing to worry about. Thank God I have been of some service to you at the time of your need. You may come to me tomorrow and I will see what can be done further to help you".
It was late at night when Umar and Umm Kulsum left. The Bedouin thanked God and said: "God be praised. I came to seek the Commander of the Faithful, and God sent the Commander of the Faithful to seek me."
