Hazrat Abdullah Ibn Umar radhiallahu anhuma

The Muslims had been in Madinah only a year when the kuffar of Makkah led a big army against them. The enemy plan was to wipe out Islam before it could strike roots. Islam was, therefore, facing the gravest challenge of its brief history. On the outcome of the coming encounter hung the fate of the new faith.
The Messenger of Allah (sallallahu alaihi wasallam) was fully alive to the grim implications. He set about meeting the challenge. He had no more than three hundred and thirteen fighting men. He led them to Badr putting his trust in Allah. As this small force was about to leave, a number of youngsters also joined it. In the inspection of his troops before the march, these lads were told to stay behind. One of these lads was Abdullah, son of Hazrat Umar (radhiyallahu anhu). He was only ten but wanted very much to fight for the cause of Allah. It was with a heavy heart that he obeyed the order to stay back in Medina.

EARLY TRAINING
The call for Islam has been ringing in the ears of the Meccan kuffar for three years when Abdullah was born. However, his father thus far kept his ears shut against the truth. But before long Umar was a changed man. He happened to hear verses of the Quran and the miracle took place. The natural pull of Islam had its full effect on Umar’s keen, sensitive mind. So far he had opposed Islam. Now he saw his mistake, he used all the weight of his strong personality to make amends for the mistake.
Young Abdullah got his early training in a home that was saturated with the true spirit of Islam. He entered the fold of Islam when only a small child. He grew under the care of a father who was noted for strict observance of the commandments of Allah. This made a special mark on his character. He became devoted to the master and as unbending in the declaration of truth as his great father. These characteristics mark Abdullah out as one of the noblest sons of Islam.

ABDULLAH THE GOOD
Abdullah was still a child when he had to flee to Medina. Tender age kept him from taking part in the battles of Badr and Uhad. But by the time the battle of the trench was fought, Abdullah was a young man of fifteen. He gave an excellent account of himself in the critical days of the siege. From then on, he fought for the cause of Islam in every battle that occurred during the lifetime of the master.
Abdullah was only a lad when he saw a dream that had far reaching effects. He was sitting in the mosque, after offering the prayer. Suddenly his eye lids closed. He saw two angels came down the sky. They carried him away to a beautiful place.
Abdullah narrated the dream to his sister, Hafsa (radhiyallahu anhaa), one of the wives of the Rasoolullah (sallallahu alaihi wasallam). She told the Rasoolullah (sallallahu alaihi wasallam) about it. He said, “Abdullah is a good man . At night he should spend as much of his time in prayer as he is capable of.”
Abdullah eagerly accepted the suggestion. He started a life long night vigil. He hardly slept at night, spending most of the time in earnest prayer. All night long he wept and sobbed for the forgiveness of Allah. Such was his devotion to his Master that he spent the greater part of the day in his company. By such extreme piety he justified the title of ‘good’ conferred on him by Rasoolullah (sallallahu alaihi wasallam).
Abdullah struck to this pattern of life to the last breath. After Rasoolullah (sallallahu alaihi wasallam) had passed away, he started weeping whenever someone talked about the Messenger of Allah. The same thing happened when he passed the historic sites where his beloved Master had fought the forces of evil. Tears streamed from his eyes when he recited the Holy Quran. In short Abdullah was an embodiment of the fear of Allah. People knew him as Abdullah, the good.

TORCH BEARER OF KNOWLEDGE
Deep piety and closeness to Rasoolullah (sallallahu alaihi wasallam) gave Abdullah an insight in to the true sprit of Islam. He could tell from personal knowledge the opinion of Rasoolullah (sallallahu alaihi wasallam) on most problems of life and the true significance of the various verses of the Holy Quran. People started turning to him for guidance ever since he came to Medina. The companions came to look upon him as a leader of faith. He lived for sixty years after the death of Rasoolullah (sallallahu alaihi wasallam).
