 If we try to thoroughly analyze this migration, one comes to know that it's not all that easy task. There are tremendous difficulties involved and root to quit Makkah and reach Madinah Sharif. If we look at these two cities and see the number of enemies on one side and two people on the other side, who have to reach Madinah Sharif with a distance of 480 km, it's not a small thing. There is no road, it's not a motorway, it's all desert mountains, somewhere it's very hot, somewhere it's absolutely barren. There is no population, there are no hotels, there are no such things that can make our life easier or we can easily stay or stay with someone. So and the journey has also to be performed by camels. Camels is very tiring. It's only the one who knows who has experienced it or who has gone through this experience. Hazrat Abu Bakr Siddiq, may Allah be pleased with him, because he had received the news three days ago, that's why you were also preparing for it and keeping things and difficulties in mind that how to perform such a long journey. You had planted 4 oentraniyas with the leaves of Babool tree. The leaves of Babool tree that the oentraniyas eat are very tired. It's very good diet for those camels. When the Prophet went to meet you, he said, I have prepared 4 oentraniyas specially for you. If you like any oentraniyas of your choice, you didn't refuse but look at my Prophet, he said to his dear friend that yes, I will take the oentraniyas, but before that I will pay the price of it. And until I pay the price of it, I will not use it. That's why you saw those oentraniyas. Those oentraniyas were for a special purpose. They were very healthy. They were capable of enduring this journey and they were able to reach Madinah Sharif without getting sick or tired. This is how the preparations for the oentraniyas were completed.
