Spend time at mosques, follow advice from parents/elders, respect elders .

This hadith is about a practice that was done by young, unmarried people during the time of Prophet Muhammad ﷺ. It is narrated by Nafi' that Abdullah bin 'Umar said he used to sleep in the mosque while he was young and unmarried. This shows us how important it was for Muslims to spend time in mosques and be close to Allah's house. It also teaches us that we should take care of our mosques and keep them clean so that we can benefit from them spiritually as well as physically. We should also remember to respect our elders and follow their advice, as Abdullah bin 'Umar followed his father's advice when he slept in the mosque while he was still young and unmarried.
