Seek knowledge & ask questions; Strive for good deeds; Show compassion towards those with disabilities

This hadith teaches us that believers who are able to do so should not stay at home and must strive to do good deeds. However, those who are disabled by injury, blindness or lameness have an exception and they can remain at home without being held accountable for it. This hadith also shows us the importance of asking questions in order to gain knowledge and understanding of religious matters. 'Amr bin Umm Maktum asked a question which resulted in the revelation of a verse from the Quran which granted him an exemption from this obligation due to his disability. This teaches us that we should always seek knowledge and ask questions when we don't understand something as it may lead to new revelations from Allah SWT.
