Remain steadfast in your devotion towards Allah & continue praying despite any hardships or challenges you may face .

This hadith speaks about how important it is to be obedient to Allah even when faced with difficulties. On the day of Al-Khandaq, the Prophet Muhammad (S.A.W) was prevented from offering four prayers but he still commanded Bilal to call for Adhan and then proceeded to pray Zuhr, 'Asr, Maghrib and 'Isha'. This shows us that we should never give up on our faith no matter what obstacles come our way; instead we should remain steadfast in our devotion towards Allah and continue praying despite any hardships or challenges we may face.

This hadith also teaches us about perseverance; even though it may have been difficult for the Prophet Muhammad (S.A.W) to offer his prayers under such circumstances, he still did not give up on his faith or stop worshipping Allah as He deserves - this is a lesson for all of us that no matter how hard things get in life, we must never forget who we are worshipping and why it is important for us to stay devoted towards Him at all times.
