You know the feeling when we know the answer to something but we don’t tell? The feeling’s called shyness. Unnecessary shyness, to be more precise..
It’s more common in kids, as it’s always been. Abdullah bin ‘Umar here was also a kid. Check out what happened with him..
Narrated Ibn ‘Umar:
Allah’s Apostle said, “Amongst the trees, there is a tree, the leaves of which do not fall and is like a Muslim. Tell me the name of that tree.” Everybody started thinking about the trees of the desert areas. And I thought of the date-palm tree but felt shy to answer. The others then asked, “What is that tree, O Allah’s Apostle ?” He replied, “It is the date-palm tree.”
The reason he tells for not answering the Prophet (SAW) is that he didn’t think it right to speak up in the presence of elders –> unnecessary shyness.
His father, ‘Umar (RA) also told him that he should have spoken up. And that he would’ve liked it very much.
Anyway, taking a lesson, being a student, remember: NEVER be shy while learning. If you have a question, go for it. If you know the answer, speak up!
